IPhone :: Wifi Drain On 4s Battery Is Unacceptable
Jun 29, 2012
My iPhone 4s is my first iPhone, and I really enjoy using it, but I was severely dissapointed when I discovered this major battery-usage flaw. Using wifi drains the battery incredibly fast. If wifi is left on, it will drain the battery (just on standby) within a day. Once I switched off wifi, it lasted over 5 days on standby. Do they know why wifi drains the battery like this, even when just on standby? Can this be corrected? I figured they would have fixed something like this by now if they could; I'm concerned it is a hardware problem that can't be addressed.

Strange that there aren't much complaints about that, but after I got the even buggier 5.0.1 update, the WiFi's battery drain is unstoppable. My usage and settings are exactly how I left them before the update several days ago. WiFi uses about 60% while the phone sleeping. No abnormal wakelocks details detected

I've had my Atrix HD for a couple of months, and am generally quite happy with it. The biggest problem I'm having with it is how fast the battery drains when I'm not connected to WIFI. Most of the time I am on WIFI either at work or home. When on WIFI the battery lasts 12 hours or more easily with reasonable use. However, if I'm on the road or out somewhere not connected to WIFI, the battery will drain very quick. For example, yesterday I unplugged my phone at about noon and was at home all day. At 9pm it still had 60% charge. I then left home for the evening, and by midnight the phone was dead. I didn't even make any calls, only checked an address on Google Maps. I did notice the phone was pretty warm during that time.
I've tried turning off WIFI and Bluetooth when I'm out, it doesn't help. It doesn't seem to matter if the phone is on an LTE network or not, as far as I can tell. I had an Atrix 4G previous to this, and never noticed a difference in battery consumption whether I was connected to WIFI or 4G, it seemed pretty consistant.

Over the last 24 hours i've notice my Xperia Z2's battery is draining very quickly, even when asleep. Even when it is plugged in charging, i keep getting messages saying the phone is unable to charge as it is using too much power. And previously i could charge the phone overnight fully, now it doesn't get close to 40%
In addition to this I've noticed it is kicking out a lot of heat at the top of the phone, and also i can no longer connect to the internet via wifi.
Everything else seems ok, and i have managed to back up my data to an sd card. I haven't added any new apps recently.
I've had the phone for less than a year and as far as i know it hasn't had any heavy drops or anything.

I know there are multiple threads out there discussing this and I looked at most of them but this is different. My 9700 has gotten great battery life since day one, but this weekend I went out to the desert and didn't use my phone much because I only had EDGE but it was dropping in and out constantly, I had a full charge on Thursday morning and when I got home Saturday afternoon I had 20% which is pretty damn good I'm not complaining about that. When I got home I charged it fully and then on the middle of the day on Sunday my batter was almost dead. Same thing Monday and same thing today. I fully charged it yesterday afternoon and this morning it was at 25% and I hardly used my phone yesterday. SOMETHING has happened to my battery life, I'm running 5.0.0593 which hasn't ever gotten me fantastic battery life but its been okay but now its just shot.
I haven't changed anything on my BB for this to happen so I'm posting here for ideas of what could be causing this, I've looked at programs running closed everything I can and do not have WIFI or bluetooth on and Have constant good 3G reception.

I use my phone all the time so I charge it everynight to ensure a full battery. However I don't want to hurt the overall lifespan of the battery. How often should I let it drain completely to guarantee a good life cycle?

Previous smart phones I owned turned wifi off when the screen went dead. So essentially wifi didn't really drain any battery and wifi was easier on the battery then 3g when actively pulling down data.
So now I am on a 2gb plan (previously on unlimited) and sensitive to this I keep my wifi on all the times to use my home connection when possible.My battery however is barely getting through a full day. My wife was getting solid days but she had wifi off.Do you think that this is effecting it? I use my phone quite a bit throughout the day.

I bought a 3GS running 3.1.3 from a friend of mine. Brought it home, used jailbreakme.com to jailbreak it and Cydia. Worked fine, put my Tmobile SIM in, made calls, downloaded apps, ect. Plugged it in overnight, got up this morning and took it off the charger at 100%. Leave it sitting and 5hrs later the battery is down to 30%! Wifi, 3g, push, ect ect are all off. Someone please help, I was so excited to get this working and now the battery doesn't even last half a day with no use!

My iPhone 4S had been working great, but after upgrading to 5.1.1 OS it is draining the battery by the afternoon every day without any or very little use. I rely on my phone for business and it can't even make it through a work day! It is draining about 4 times faster than normal. I found a post referencing to 'Reset All Settings' which I tried yesterday, but it still is draining fast. I tried resetting, rebooting, shutting down all apps, but nothing helps.

Nexus 5, 16GB, MRA58N (stock, not rooted). Sometimes the power percentages shown for each process in the battery monitor do not add up to the total battery drain? I am finding that sometimes they add up to within 1% of the total shown.... and sometimes they are WAY off with as much as 30% of the displayed battery drain unaccounted for. Since I don''t have access to the battery terminals, I can't determine independently whether the percentages shown are simply inaccurate, or whether there are missing processes (ie., processes not shown at all in the battery monitor).

I plugged in my ip4 last night a couple hours before going to bed, and noticed that it was up to 100% when I went to bed. I woke up and, still plugged in, was at 97%...?Is this normal by any means? I mean, I know my MBP which I always have plugged in will drop charge while plugged in to such %'s (97,98,99).however my ip4 has never done this before.

My iphone 4S drain the battery too fast.Bought the 23 dicember 2011, it has just 4 months of use and the battery should be gone? I think there is a great software problem.and Apple had to fix it definitevily. A product like this, with this price MUST CAN BE USED AT LEAST 2 DAYS IN ALL HIS FUNCTION!This is a device thinked to be connected everywhere at everytime, but the hardware seems not to follow this intent. I used the phone for calling, sms, web, mail and music, NO GAMESail has no push notification.Yesterday I've disabled all notification and some other things to see if the battery could be better, tried to not recover the old back-up

A week ago I realised that my phone was heating up rapidly and my battery was being drained alarmingly fast before days end. I used to go a whole day and would only hit 50% battery use. After some research, reading and testing of my own, I can say with some certainty that after turning off the push notification and location services on my phone battery life has dramatically improved returning to pre update performance and the overheating has ceased.

I have recently bought a new iphone 4s- 16gb. Updated it to 5.1.1 version.
The iphone has major battery issues. I charged one night and morning it was drained. It was only on wifi.
Also, while on wifi - the battery drain is too much. The standby time and the usage time are generally same.
- Location was off
-Bluetooth off
- wifi on
- Emails on
The drain is very fast. Next - the apps like facebook, contacts, watsapp etc carshes quite frequently.
I installed an app called 'Battery Doctor', in the stats i found that the CPU usage is very high even wiht only 1 app running. similar is the case for RAM usage.

I want to have Notifications on in order to use Find My iPhone using MobileMe. Does anyone know if having Notifications on while having Push off for every App and email account affects battery life? I know that using Push drains the battery but don't know how having Push on but not using it affects the battery.

so is there a way to "close" and app instead of it "minimizing" in the background I know you can double tap home, hold an icon, and then close it that way" but this is quite the hastle doing this every time i exit an app..and im sure the more apps you have in your "minimize tray" the faster your battery drains... correct?
have you guys found any way to close an app with out it minimizing? or even an magic "remove all" button to close all open apps...

Upgraded to iOS 5.1 a couple weeks ago and since then battery drain has been horendous. Have problems on my iPad 1, have problems on my iPhone 4S, but iPhone 4 seems not to be affected as badly. I have disabled options and disabled apps (though they should be paused and not draining the battery) to no avail. Disappointed and think I'll go back to my iPhone 4.

I'm not here to report a problem. I'm just asking, out of curiousity. Yes, I've seen all the threads, and read the obligatory items on optimizing settings for power saving. Heck, I'm a "battery miser". I have no problem with premature battery drain. In fact, I'm a "light" user of my iPhone 4s, and have no problem getting an unusually long time out of a charge! Perfectly satisfactory.
However, I do *not* have Siri turned on (fear of battery impact). I was thinking of "toying with" Siri. But I haven't found, anywhere, a discussion of the affect of Siri on battery drain. Before I bother with an experiment, may I find, read, and benefit from the experiences of others in such a pursuit? Does Siri exact a heavy toll on the iPhone battery?
