Samsung Galaxy S II :: How To Increase Battery Life
May 11, 2011
well every phone needs one right? and i just noticed a few things that this phone has that the s1 didnt, sooooin Voice Talk, turn off 'Wake up command', when voice talk is running, your microphone will be constantly on listening for you to call "Hey Galaxy!" (wake up command)double press home>menu>settings>voice talk settings>wake up commandturning vibration off, believe it or not, vibration uses more energy than max volumelimiting how much processor is used, an app like SetCPU can limit how much processor is used, and in what way, setting your processor to Conservative will increase battery life. turning off bluetooth and wifi when youre not using it will save unnecessary searches for signal turn off automatic background syncing make sure you fully close out an ap, either by hitting back till it closes, or menu>close poor or no signal will decrease battery life, as your phone will constantly be stressing to find a good signalif you really wanna go crazy use a solid black wallpaper, it wont use any LEDs at allont use live wallpaperssingle best thing you can do for your battery: turn brightness to 0, this is the difference between 6 hours of use, and 2, the s2 has an amazing powerful screen, and it will drain the battery if its maxed. download 'Brightness Level' an easy widget from the market used to quickly adjust brightness between when you want to show off, and when you want to be practical
I’ve got a BlackBerry Curve 8900 (ATT, running 4.2.0.108), and have had it since Oct. 2009. Battery life has always been OK - 24 to 48 hrs. between recharges.
Today though, after pulling it off the charger this morning around 8:00 a.m., I’ve noticed that I’m down to about 5% charge by 2:30 p.m. I have made no phone calls today, and have only sent/received a couple texts and rec’d two emails. I've never used a holster, have downloaded no apps, Bluetooth and Wi-Fi are both off. No keys appear to be sticking. Absolutely nothing, to my knowledge, of any significance has changed on the phone since October, yet all of a sudden --literally, overnight --I am experiencing this greatly diminished battery life. The only even remotely precipitating factor I can think of is that I did a battery pull yesterday, after deleting some old photos and emails.
I’ve searched the forum, and most of the suggestions are along the lines of “turn off bluetooth/wi-fi/update OS,” but as noted, I never used those anyhow, and the OS has always been good to me.
Does anyone have any issues with the battery life on this thing? I just picked mine up from Bell about a week ago, and standby lasts maybe 48 hours. Its rated @ 250 hours and although I wouldn't expect to see that, this is a little ridiculous. 48 hours is sitting only. If I make a couple of calls, its basically dead in a day. This is with GPS / WiFi and Bluetooth disabled. The only aftermarket programs installed are Barcode ( which doesn't run when off ) and TaskPanel which allows me to kill background processes.
What I notice is that if I run TaskPanel and kill everything, and then the phone goes into standby. When I wake it back up and run TaskPanel again, I see Alarm Clock and Calender are running in the background. Neither have any stored events and I don't know if they are kicking in on wakeup, or right before standby and thus running in the background and killing the battery faster.
I recently purchased my s2 and love it coming from a fist gen iPhone. Only thing is, I have been having trouble getting my phone to last all day. When I checked the battery usage it says Logcat is taking more usage then anything else including my screen. Ive never run this program, as apparently its for debugging code or something. I have searched around the net and only found one post that recommended factory resetting, in this persons case caused by a bad app.
Does anyone know the effective battery life time when playing 720p h.264 mkv files with 100% screen luminosity and almost all the other features off (wifi, bluetooth, internet, etc)? Also, is there support for subtitles? I am debating on what to buy, the Galaxy S or the IPhone 4. I need 3.5 hours of video playback between charges. I want to eliminate the video conversion step, so if the Galaxy S can eliminate it, that would be perfect.
my battery is around 30% at the end of the day (average since owning for 2 months). However, 1 day last week I got the force close box come up for TW launcher as I took the phone off charge first thing in the morning. That day my battery was at 52% at the end of the day! I left phone turned on and charged as normal, next day the same, around 50% at end of day (same useage as always, same environment etc). So, next day I turned phone off / on and at end of day battery was around 30% again. To confirm my suspicions I force closed TW launcher and the next day back upto 50% remaining again...
My phones memory is almost full so I got an sd card and put that in but how do I go about transferring things to the sd card to free up the phones memory. I am thinking that moving some of my apps would free it up the most. Is this possible. If not what would be the best option.
About 10 days ago, my Samsung R451C (Straight Talk) battery went dead. I thought that was odd, since I generally got four or five days service out of it before needing charging. So I put it on the charger and charged it up, and about six hours later the phone was dead again.I then purchased another OEM Samsung battery. Same problem; the phone needs recharged after five or six hours. Also, while fiddling with the phone, I noticed that I can no longer shut the phone off by pressing the PWD/END button--it shuts off and then immediately reboots back on.I called Straight Talk support and described my phone's battery life and power button symptoms. The rep immediately stated that Straight Talk would send me a replacement, making me wonder if there's a hardware or firmware problem in the phone they know about. However, the catch is that I have to send in my phone first and then they'll send the replacement, about a 15 day turnaround, according to the rep. I really don't want to be without a phone that long, so I'm looking at alternatives. Anyone have any experience with this sort of phone behavior before and have any suggestions for things I might try before sending the phone in for replacement?
My wife and I are looking to switch to Sprint and she is interested in the Samsung Moment. I have read many reviews where the complaint is the short battery life. Most of the reviews are older and I'm wondering if the phones with the newer firmware and 2.1 installed have a better battery life.I appreciate anyone with a Moment running 2.1 provide feedback on the battery life.
I am really enjoying my Samsung Captivate. As a result I find myself running out of battery life during the course of a day. Beginning the day with a full battery, I only get about 2 hours of web browsing time, when doing browsing only. At that point I've only got about 20% battery left for making calls or sending email. Anyone care to comment on your Captivate Battery Run Times?
I had my Samsung Galaxy s6 G920F one week ago, nothing to say about the phone, amazing battery life. I always plug my phone to charger when I'm home after work, I don't leave it plugged while I'm sleeping. During the night the phone consumes like 1 to 2% battery. I shut down wifi, bluetooth and data during the night. Two days ago I installed Adobe acrobat reader, and disabled some built-in apps which I don't use (Google play music, google newsstand, chrome, hangouts, google+ and skype). Before I go to sleep my phone was 82% battery. When I woke up, my phone was 64% battery. I thought that the issues with Samsung/Android battery life are over with android 5.1.1 and galaxy s6, but in fact no.
I found that a clear cache can solve my issue. I did this and battery drain stopped. Yesterday night, I decided to make a full wipe/clear data, and clear cache. I reinstalled same apps that were on the mobile before, and disabled the same built-in apps. Phone was at 74% when I went to sleep. This morning, my phone was at 52%!!! So I uninstalled Adobe Reader, and activated all the apps that I disabled before, restarted into recovery and cleared cache. Now the issue disappeared again, but I wonder if this will not appear again when I charge my phone to 100%.
I've had my Galaxy s6 for about a week now and I've been very satisfied with my phone. One weird thing I've noticed...Instagram seems to be using a ton of my battery life. I'll usually get around 16 hours or so on my battery, which I'm definitely satisfied with, but when I check my battery stats at the end of the day, Instagram will have used over 15%+ of my battery life. I have tried closing the app every time I switch out of it. I've tried Force Stopping the app, but it seems to continue to drain the battery in the background.
Could this be a glitch with the battery stats? Or is Instagram really using that much battery life? It's by far my largest consumer of battery and I hardly use the app..it's a bit frustrating. I don't want to uninstall it.I have been vigilant about keeping Instagram closed and it still seems to be using up my battery. The problem is that it seems to be using battery (assuming my battery stats are correct) even when I don't have it open.
Was using 5.1.1 after update and was having a few little issues, nothing too bad, the battery was acceptable. I did a factory reset to try and iron these issues out..... phone now is better however the battery has taken a large hit.
Nothing obviously causing it. All looks normal, when I have charged fully the battery info shows estimated battery at around 9 to 10 hours brightness set below 50% . It's a bit annoying when you do everything to manage it. Was fairly happy before but now... didn't know if it's feasible to keep.
So out of curiosity, what default apps/services do you have disabled to achieve the best SOT? I've been experimenting enabling/disabling some applications and it seems to directly impact battery life.
For instance disabling "Samsung Push Services" seems to bring a little boost to battery performance.
Carrier bloat aside because that's a given to be disabled.
I upgraded to a 64gb SD card, roughly two weeks ago, and I had several problems trying to transfer all of my music and pictures and whatnot over to it from my 32gb SD card...ended up losing a lot of them because of having to re-format the card (I have a memory card recovery program on my computer already, so losing things is not a concern at this point) .
HOWEVER, my phone fully recognized the 64gb card immediately, once I properly formatted it and whatnot, but only for like a day, then I started getting error notifications that the card was not properly inserted, or the phone was not reading it, etc...the card has been inserted into my phone for about 10 days at this point... a friend of mine also has the same phone as I do (s5) and it reads just fine, as does her card in my phone, so clearly it doesn't seem to be an issue with the card itself, or the card reader slot..since other cards are registering..?
Then there's also the issue of my battery randomly draining unusually fast the last few days...and this has only been happening over the last three days...I did go to Sprint two days ago and they "primed the battery" but it did not work at all (battery life went down from 87% to completely dead in less than 5 hours last evening)...
I like to use my phone until the battery dies but the phone goes into power saving when under 5% battery life and I can find no way to disable it in order to adjust brightness or use the light.
I posted about a problem with my battery losing up to 30% battery on reboot but got no answers so am hoping somebody will test their phone for meWhen my battery drops to just below 50%, if I reboot by pressing and holding the power button for about 8 seconds, on reboot, my battery has dropped to as little as 13%, even if there was 48% left prior to rebooting.I originally thought this was happening after tethering but it has turned out, it does it regardless of how much or how little I use the phone and even without tetheringI am on stock 2.3.4 XEU, manufacture unlocked and wondered if some kind soul would be kind enought to see if they can replicate the problem.It needs to be the 9100, complete stock and not rooted really as I am trying to determine whether it's a hardware issue or software issue.
I have already read enough of this great forum post, I hope in the future to helpbeginners like me, one day we had to IOS (formerly had a Galaxy S2) and now we are more than comfortable with my 4s!I have the cell phone constantly charging, either in the Dock, when I go to bed, Through The cable in my university (when I'm in class or on the computer in the Library), this because the phone if consuming battery (I have the iOS 5.0.1) and hate running out of battery (no phone) when I'm away from home.Then the doubt (I've already searched in many forums) is whether this is detrimental tothe battery of the phone, or simply when the iPhone detects that is loaded, just stops receiving load and nothing happens:
So had my N900 for a little over a week now and overall I'm pretty impressed. Great phone, but still very much a work in progress. One of the main issues I have at the moment, other than no turn-by-turn navigation (sorry, had to mention it), is the battery life - or lack of!
On an average weekday I use the phone to send a few texts (no more than 10), scan the news sites (no more then 20-30mins total) and catch up on my RSS feeds (again, no more than 20-30 mins total). I'm not using the media player at all and I may make one or two short calls.
Bottom line is that I'm struggling to get more than 6 hours battery life out of it. I know smart phones are thirsty, but I don't even get to listen to music on my way to or from work!Here's what I've already done to reduce battery consumption:
Removed active widgets (such as ForcaWeather) from desktops and replaced with web shortcuts.Reduced screen brightness to 2 barsDisabled GPS & Network positioningDisabled IMDisabled BluetoothI've heard some mention reducing the amount of active desktops, but I think that kinda defeats the object of having a N900. May as well buy a lesser phone if you need to strip out all the functionality to get though the day. I'd be satisfied with 8-10 hours medium use. At the moment I'm getting around 6 hours at light use - got to be something I'm missing.
know the battery capacity of the XOOM (MZ601), mine is 3260mah Reason for the question is my xoom, replaced about a month ago used to give me 5 days life, now its 2 days, and thats just scraping in.... No SD card, same apps, same usage pattern
I gave my sister my old curve its about 1 1/2 yrs old. the day i gave it to her the phone worked just fine but after she flew back home the battery would only last her a few minutes. i told her to try a new battery but it still has not changed anything. i even got her to upgrade to 5.0 just to see if it would make any difference but it doesnt.
she barely uses any apps, and mostly uses the phone for emailing.on standby it will every 10minutes or so the battery life will go down by 10%, and after a few texts or a minute or two on a call the phone will just die. she can pretty much just use it when its connected to a power source.Seems like a phone issue but there is no warranty on it
Okay, so I'm on the move a lot, travelling to and from University each day which can take anywhere between 1-2 hours getting there and getting back. I'm always on my phone during travelling as there isb't much else to do and I like to keep in touch with friends. I use Facebook and the internet a lot on their and I understand this is why my battery runs down so quick. Using it for I'd say 3 or so hours and the battery is done, I usually take my usb cable to uni so I can charge it ready for the journey home. Is there anyway I can get the same usage out of it and not drain the battery so much? I am thinking of getting a new battery first off as I'd say the current one would not be able to achieve good life againt, but is there long lasting batteries I can get?
Just purchased iPhone 4S and it's sucking the life out of the battery. I've read several posts to turn items off to save battery life and nothing seems to be working.
