IPhone :: Lost %50 Battery Life While In Standby
Jun 2, 2012
I noticed that after I installed the latest IOS 5.1.1 the battery life seems to deteriorated over the course of 1 week use.
The strangest thing happened yesterday. My phone was on %9 battery life and I decided to keep it as I was out and I put it in my pocket. In less than 10 minutes I pulled it out and it was dead, no responce. It actually chewed %9 percent while being on standby. No extras were turned on, bluetooth was off and wifi was off too.
Last night I went to bed and my phone was %53 percent charged and I left it locked next to my bed. I woke up this morning finding my phone completelly dead?
I will monitor it closelly over the next week but I had it for a year and this had never happened. The only common denominator is installing the new IOS.

I was just wondering what everyone else's experience with the battery life was. What's your best standby and usage time and was it with push email on or off?

Finally got around to sticking my SIM card into my 6P and decided to leave it off the charger over night to see how much battery percentage it would take away. I fell asleep with the battery at 55% and awoke with it around 30%. Looking at the battery usage, cell standby is consuming more of the battery than anything else. I've seen this bug in previous versions of Android, but have not heard anything about it with 6.0. Is my phone bad?
I'm on Verizon if that matters at all.

I have a user with a E72. It has the most up to date firmware. The user is finding that the battery does not last very long. By mid day the phone is almost out of life. He is not making lots of calls. Life goes while on standby. We have also brought a new battery, still has the problem. The battery is a genuine Nokia battery.

I checked the info under General > Usage and the "Usage" and "Standby" are exactly the same, which I am assuming means it is not really turning off when I am not using it. Is there a fix so my battery doesn't deplete in 8 hours?

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.

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:

I've set up my iP4 as a New phone and did NOT restore from a previous backup. I did a full charge to 100%, reset the data usage and made sure all apps were closed. I put it the phone to sleep (clicked power button) and I went to sleep. I woke up this morning and woke the phone up; 4% was used after 6hrs and 50min of standby time, there was no other usage.
Doing some quick math this would equate to 170.83 hours of standby time assuming a linear relationship; 56.94% of the 300hrs on the spec sheet.
410min/4% = 102.50min/% of standby use
102.5min*100/60 = 170.83 hours
This seems pretty light given the standby time rating. I'm hoping I can get others to perform the same test to get a decent sample of performance, please post your findings.

For last 2 days now my iPhone hasn't been holding its charge, even in standby mode.
I took screen shots of it earlier and at 5:54am whilst in work the battery was at 82% then it stayed in standby in my pocket until the next screenshot I took and the percentage was falling fast, by 9:28 the percent was at 1.
Does anyone here know if there is anything I can do? I have restored the iPhone and also let the battery charge up to 100% from no charge in it and to no avail!
The phone is only a month and a half old and nothing has changed since the last 2 days so hard to understand why it has started doing this, brightness has always been at 100% so that's not affecting it.

My wife's 4S has been running down about 50% overnight in standby so I decided to investigate it. The basic problem is that it is showing a usage figure of almost the same as the standby figure while in standby indicating that something is running. After trying all sorts of things (including a restore), in desperation today I restored her backup to my 4S and my backup to her 4S. The problem remains with hers which is really strange indicating a hardware problem, but the fact it is showing too much usage would indicate software.

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.

I installed 4.1 on 3GS yesterday, and it feels like I've got better battery life or at least more accurate battery reading. After about a day of usage, i hardly used to get about 40% remaining at night, but today, I've got it on 54.

Last night I charged my phone to 100% from a dead battery, was finished around 2am. I used twitter and played a little fruit ninja, made a couple calls today and used some WiFi. I turned on my battery percentage and it was 47%... Pre 4.1 I would still have around 70% left.

I upgraded to iOS 4 last week & now my battery life is about 1/2 what it used to be.
It used to comfortably last a day, now it last about 1/2 that - I definitely have to charge it while at work each day.Anyone else found this?I'm hoping some solution can be found & slipped into an update - this handset is only a year old, so the OS upgrade should not have quite such a dreadful impact.

I have put my iPhone to 0% then charged to 100% three times now. Before the third time, I downloaded battery doctor. It seemed pretty cool that it can show me how much time everything takes, so I decided to check again after charging to 100%.
When checking, I see that everything is lower than it should be. It's actually comparable to a 3GS, and not my 4.
(URL)
For example, battery doctor says my phone can have 30hr audio playback, 5hr talk time on 3G, and 3G internet time is 5hr. This is all comparable to the 3GS, which really disappoints me.
Is it giving me 3GS times because it identifies my phone as an unknown phone, or is there something wrong with my battery?
If it helps, IIRC I had around 7 hours(maybe a bit more) of usage, and 1 day 19 hours on standby right before it went to 0%.
