IPhone :: Cerebro Is Such A Battery Hog - Only 1 Hour Of Usage
Feb 1, 2010
I installed it last night because it looked interesting. Similar to the MobileMe Find My iPhone but free. Anyways, woke up today (8AM) to go to school. My classes are from 8:30AM-2:15PM. I only have a 1 hour break in which I listened to Slacker radio while I used library computer.
When my last class of the day came around, I saw my battery meter, 8%! It then died 5 minutes later without no use whatsoever except that 1 hour of Slacker Radio and that's all!Nothing was running in the background or anything! So I warn you guys if you install still that it will SEVERELY bring your battery down.

I've gone through 5 Lumia 1020's in the past 3-4 weeks. All having the same problems with battery life. After taking my phone off the charger, I turn off Bluetooth and WiFi. I don't have glance on but I do however have all my background tasks running. I have two emails set to sync as arrive, Hotmail and outlook emails. I took my phone off the charger at 6:30 AM this morning, and when I looked at it an hour later, 7:30AM, I had 90% battery left. I have 3-5 bars of LTE and 1-4 bars of 4G everywhere I go. I do a soft reset 3-4 times a week since this is a common occurrence. I just took my Gmail email off my phone, so I'm testing to see if that was the problem. I normally get 9-11 hours of battery life, but I need to get 14-16.
How to possibly improve my battery without limiting the phone to what it's suppose to be? What I mean is, WP is based around live tiles, if I stop all the tasks, then it's just a close version of iPhone with limited apps. I don't want that. I don't like iPhone or android.

Since yesterday (12/20/15) my 950 has been running very hot and the battery drain exceeds 25% per hour. It was fine after the .29 update a few days ago, this just stated happening. I've done all the normal things, turned off a number of background aps, location off, soft resets, no updates occurring that I can find, etc., phone is hot when not being used and very poor battery life.

Not seeing anything anywhere about this; I'm sure I'm over looking it, but starting today I seem to be getting almost 25% battery drain per hour. I've used my phone very little today, so I'm not over using it. This started this morning and I've had the phone since the 8th I believe(ordered online)

Ever since I got my defy I was very impressed with the battery life. After the group update I found it shortened slightly compared to with eclair but still good This weekend its suddenly started discharging at a crazy rate! I've twice tried hard reseting the handset but it continues to discharge quickly!I run very few applications. The major 3 being whatapp. Facebook and twitter.

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.

Standby: 16 hours 33 minutes
-Wifi on for about 3 hours
-1 exchange push email
-Brightness about 40%
-1-2 hours of games
-An hour iPod
-20 minutes 3G talk time
-Texting/Checking twitter

Over the past week or so, I've noticed that my Iphone 4 battery seems to be depleting faster than it had been previously. I've also noticed that my usage time seems quite high, based on my actual usage.To test this a bit, I unplugged my phone at 100% this morning, confirmed that the "time since last full charge" counters were reset, and left my phone untouched for the next 3+ hours. After that time:
Standby: 2hrs, 41 minutes
Usage: 1hr, 13 minutes
Battery: 95%
I do have 3 email accounts configured, with the polling interval at 30 minutes. Push email is disabled.How would I have racked up 73 minutes of usage without touching the phone? I've tried rebooting the phone, but that didn't seem to have much effect...

Since iOS 5.0.1 I never had. Artery problem. But after recent upgrade to 5.1.1 I found that while using usual apps, including very simple like card game, my iPhone became very, uncomfortable hot near sim slot location. I was tried to reinstall sim card several times - no effect. Battery drain now terrible in active mode, about 1 percent per one or couple of minutes.

Everyone always says that using bluetooth etc can be a major drain on your battery power. I want to know exactly how much of a drain on battery power using bluetooth is. If the iPhone were to be subjected to constant bluetooth data exchange for, lets say, 1 hour, how much of an affect would this have on power.

My iPhone 5 64GB is not working as well as I think it should be. After about 3 hours of usage (according to usage statistics in settings), which is just Facebook and web browsing, and 9 total hours of standby, the battery dies. This is mainly over 4G with medium brightness. Background App Refresh is off, most location services are off, Push emails are off, reduce motion is on. I have tried everything I have found online to try and fix this, but nothing has worked. On top of that, my iPhone was just replaced at an Apple Store, so I'm not really sure what it could be.

I just went to the gym and had my phone playing Groove Music to my bluetooth earphones, 20 volume and screen off the whole time.
In one hour it went from 86% to 63%.
On my 1520 with W10 insider build, music on SD card and same earphones it is not as bad as this.

So I've noticed a problem with my iPhone 4 draining itself...even when I'm not using the phone at all. A couple of nights ago, I charged my phone up to 100% and left it in standby overnight. I woke up the next morning and the battery was at 53%. Last night, I charged it up to 100% again and did not touch the phone at all until this morning. When I woke up, the battery was at 83% and it reported 19 minutes of usage even though I did not touch the phone at all.
But it doesn't drain itself all the time. Sometimes standby battery life is great but never excellent. Then when I use the phone (safari over 3G or wi-fi, ipod, light gaming, etc.) the battery drains at about 1% per minute. Is this normal?...all of this continues to happen after I've restored and set up as a new phone multiple times. Anyone else having these problems? Think it's a hardware issue? I'm a little jealous of all the other iPhone 4 users out there who report stellar battery life.

I'm on my second iPhone 4, since my first one had the yellow screen blobs. The battery was great on my first one, but not so good on this one. I restored the same backup, and even did a settings reset to get rid of anything that may cause an issue.
What's weird is that when I check the usage in Settings > Usage, the standby is correct but the usage is creaping up without me actually using the phone. For example, went to bed last night and usage was around 3 hours and battery level 55%. This morning, it was 3.5 hours and battery was down to 47%. I'd even restarted the phone before going to bed so that nothing was running in the background.
I'm just DFU restoring my phone to see if that helps. And I might delete and re-add my Google Apps Exchange accounts incase there is something going on there.
