Q: iPhone 4s Battery Life?

ios 5 is still have battery issue

I am now, as of this morning, on 5.0.1 - 9A406.

The problem I mentioned with the 1% with an hour's usage or more was with 9A405.

I've yet to see how battery life has improved or degraded with the new firmware.

I don't get above 5hrs and 30 mins of usage and 1 day of standby. I usualy get 5hrs of usage and more like 16hrs of standby then my battery will be deplited.. Is this normal? I mean I only play few games, few messages, and 2 hrs of 3G.

Look further down in the message. I recalculated using just wi-fi spec. He said wi-fi was turned on all day and used 30 min of talk time. So 6 hr 51 min- the 30 min talk  (6.35) was all internet use, browse,imessage etc then divided by the wi-fi spec of 9hrs instead of 7.5. The first calculation was with the wi-fi /3g average but clearly that was not correct as it came out to 113%. The wi-fi assumption calculated almost perfect at 99.25% plus the 1% he had left.

And yes, I agree,  the 3g/wifi avg should be used when not known. (why i redid the calculatons)

I'm quite tired today but I don't understand how you came up with his 6.35/7.5 for 3G/wifi - he didn't disclose where the 2.2 (6 5/6 - 4.5) other hours went - but it seems he was only using the UI during that time - or are you basing this on a prior post which I didn't read? You seem to infer he was using the device over 3G/wifi for (total time - 3G calls). I believe first of all you and davidch's estimation of 7.5 is useful for undisclosed usage to profile the results for a mixed 3G/wifi internet use, but it should not be used when the usage protocol is disclosed by the user. Here he said 3.5 safari and 0.5 iMessage - hinting to wifi only from what I can read. So this would be 4/9 = 44% +22 + 6 - 1 = 71% - if I'm right this simply points to a not unreasonable yet superior that 0.5 standby drain, most likely close to 1% (mail, low power state apps what not). Or am I an uncreative barista?

For me wi-fi does not make a lot of difference as I tried it one day just to see. It was about 5% or so less remaining (so used 5% more battery). I believe folks who are suggesting to turn off wi-fi to help battery are suggesting so if there is no wi-fi available as the spec is for 6 hr over 3g but 9 hr over wi-fi. I have turned off the "ask to join" but leave wi-fi on all the time. I suppose its still looking so when you are in a preferred area it connects but again I am almost always near some wi-fi source. Certainly when ask to join is on, driving though a subdivision its popping up constantly with the available networks.

Siri off? are you saying totally or the raise to speak option?

3.5 hours safari (wifi), 30 minutes imessage, 30 min talking. in the rest 2-2.5 hours I was like takeing some pictures, setting the Settings, looking at pictures, checking the battery etc. NO games or music.

 

p.s.: did 2 restores and setting time zone and siri was OFF. everything else was ON. (3G was enabled too. but I was home so I used wifi)

just charged at 100% trough night so now I will disable wifi and I will try just with 3G on. see how big's the diffrence.

grrrrrrrrr

siri was totally off. i'm not using siri at all. in europe is worthless...

why? makes big difference?

Why does my iphone never give me usage data? I've had the phone 6 weeks or so, it's been fully charged plenty of times already but continues to say "Usage times will be shown after iPhone is fully charged".

It appears that turning off the raise to speak function helps due to the sensor always being on when the phone is active (not asleep). I see no reason having Siri turned totally off would help other than if its off, the raise to speak is also off. I don't believe Siri is doing anything until you activate it.

Are you removing iot from the charger when it hits 100%? The fully charged state happens a while AFTER it hits 100% so you have to leave it a bit longer. At minimum until the lightning bolt turns to a plug. Otherwise maybe a hard reboot is in order. (sleep button and home button at same time til phone shuts down)  If you do the reboot it will not show again until fully charged.

Hi sbailey

I've left it sometimes 2 hours longer in the charger after it shows 100%.

I've also left it overnight on charger.

I've done the run down till it shuts off several times already and then recharged to 100% and beyond.

I've done several hard reboots too.

Cannot figure this one out.

I have already ran over 24 hours with 9A406. Here is the status at 24h mark:

Standby: 1d 00h

Usage: 1h 37m

57% battery remaning

During this time, 3G was always on and the Bria VoIP application was started (it does sleep in background, but the 3G connection to Internet stays up all the time anyway).

I made and received several calls, around 20-30 minutes talk time.

Not much other use, except few Mail invocations (I do not use Push Mail). My mailbox on an IMAP server is however HUGE (few million emails) I wonder how that impacts Mail, as it seems - not much.

I woke up the iPhone every hour or so to check remaning battery.

In the first few hours WiFi was on.

So far this looks better than my 'mostly standby' experience with 9A405. I will report back on more extensive usage, although it was the "standby" quick discharge of the battery that bothered me before.

Also, I guess the Bria VoIP application might be draining the battery faster when talking. I noted than on longer calls the iPhone will become noticeable warmer. I decided this might be because I used the "GSM" VoIP codec and have switched that off. It seem that the integrated Phone does not consume that much during calls.

Anyway, over 2 days with constant Internet/VoIP connection on doesn't sound bad.

I would say next step is to try a restore in iTunes. It will offer to backup data, restore firmware, then restore your data. Probably try that first. Then as a  last resort restore in iTunes and setup as new phone, not restoring the backup. Of course you can still sync with iTunes to get contacts, apps etc back but data will be gone.

I've been following this thread since October and it appears to be largely an exercise in futility with thousands upon thousands of recommendations that don't ultimately work for most complainers. Apple aught to bite the bullet financially, admit they have a problem they don't have a work around or solution to, and offer a free upgrade from this model to the 5 when it comes available. I'd recommend sticking to earlier models and getting refunds where possible

I think I have solved battery short life after restore iOS.

Before this I tried everything. Turning off all features don't help. I have had 7-8% battery drain every hour.

Now, after restore, the hourly draining is about 2-3% with many features turned on: 3G connection, some notifications, location services, automatically setting for time, push notifications for gmail app...
