Q: How I fixed my 4S battery problem

I do understand that most people will not have the time or will not bother reading through all the advice given in the massive battery problem thread. So I just want to repeat my experience here and I hope it will help someone.

 

 

-------------------------------

 

 

Ok, my 4S is now working completely as expected.

I'm not sure which step did it in the end, so I'll just repeat my experience.

 

FIRST ATTEMPT:

 

I did the 'recovery mode' restore first (google for 'iphone boot recovery mode'  to learn how to do this). After which I started from scratch (using a 4S backup should work as well) and disabled the often mentioned notifications (disable calendar) and location services (disable time zone) that seem to cause trouble.

 

After that I did a full discharge and charge of the phone.

 

That made a huge difference. The phone still discharged too quickly but it was A LOT better than before, especially when actually using it (as opposed to it being on standby during the night)

 

SECOND ATTEMPT:

 

And this is where the magic probably happened.

 

I did a 'restore settings' (which doesn't wipe the phone: General > Reset > Reset All Settings), disabled the usual notifications and location services again (see above).

 

I then used 'Battery Doctor Pro' to do a charge with trickle charge.

 

Went to bed, phone 100%.

Woke up, phone 98%

 

4hrs later with moderate use (email, texting) but lot's of driving (so network searching)

Phone 93%

 

-------------------------------

 

Latest update:

 

I did my second trickle charge yesterday evening. Went to bed (battery 100%) woke up in the morning with the battery still showing 100%

 

8hrs later with fairly heavy use (emails, calls, text) and mast jumping (driving), notifications, Siri and location services switched ON.

Battery 80%

    Will the reset mean I have to start re-training Siri all over again?

     

    No, the information Siri collects to improve voice recognition and give context-sensitive responses is stored on the Siri server, not on your phone (which is why you need a network connection for Siri to work).

    I probably had about 60% left with that amount of usage.

    Not quite there I would say.

     

    Are you sure you did the settings reset under general > reset > ... before doing the battery thing?

     

    Could just be one of the notifications or even Siri or something. Maybe your location makes a difference. I'm in the UK.

    Qucik question.

     

    When you did the reset of all settings did you start from scratch as a new phone or restore from a backup?

    Btw, the 'settings reset' only deletes settings, it doesn't wipe the phone. So no need to start from scratch (you just have to set up certain apps again and settings again). It shouldn't matter whether you did a restore from backup or started from scratch before doing your reset.

    I thought I chose "reset all setiings", but somehow I ended up having to choose to restore from either an iCloud or iTunes backup.

     

    I chose restore from iCloud backup and obviously everything went back to where it was.

     

    Did a skip over a screen somewhere in the process?

     

    BTW I am now at the following:

    25% remaining

    1 day, 9 hours standby

    5 hours, 38 mins usage.

     

    I had 3 location based reminders on for the best part of the day today so I don't think those figures are too bad considering.

    The icloud/local restore is an optional step.

    I know it does look as if you have to restore but just skip it and you'll find that all your stuff is still there.

    Cheers, I'll give that a go before I head to bed and then recharge. Should be under 20% by then.

     

    I'll update - again in a few days. Are you still getting good results?

    Only discharge 1% overnight.

    6hrs of pretty decent use now and 85% at the moment.

    Wow, sounds like you're over any problems.

     

    So only overnight at almost dead? I didn't know that.

     

    I'll charge for a bit before bed then unplug. I'll try to run it down to nothing during the day tomorrow and do a full charge plus trickle tomorrow night.

     

    Thanks for your input.

    FYI here's my latest update:

     

    Now on 5.0.1 and it seems about the same as 5.0 for me and overall I'm reasonably satisfied with better life

     

    With most of the time on wifi apart from about 5 hours on 3g here's what I've done - a number of short calls, half a dozen text messages sent and received, read and received about a dozen emails, location based reminders current for about 3 hours, around 2 hours online and using twitter and Facebook, played games for about half an hour, and about half an hour playing with settings and Siri - my usage is:

     

    Standby time = 1 day, 12 hours

    Usage time = 4 hours, 50 minutes

    Battery left = 39%

     

     

    My current settings are:

    Mail: iCloud and Gmail accounts both set to 15 minute fetch

     iCloud: mail, reminders, contacts, calendars, notes, documents, photo stream

     Notifications: phone, messages, reminders, calendar, cnbc, mail, twitter, find friends

     Location: maps, siri, weather, reminders, twitter

     Sytem services: all off but Mobile Network Search is on.

     

    Will let you know the final result when battery drains.

    Okay, before heading to bed and leaving phone to recharge overnight.

     

    Battery remaining = 1%

    Standby time = 2 days, 2 hours and 15 minutes

    Usage time = 7 hours

     

    All in all I'm pretty happy with that and seem to be getting what the specs say as far as usage goes.

     

    A 10 minute call today used 2%, that would equal about 500 minutes to use 100% which comes out at just over 8 hours - pretty much what apple say to expect.

     

    Hope everyone else gets sorted.

    I thought my battery drain issues were new with the 5.0.1 update, however after reading the above posts, I realize I never had that great a battery!!!!   Daily use, mostly standby time at work for 4-5 hours, texting numerous times throught the day, emails being pushed to phone, occasional internet on 3g at work, use WiFi at home. Here I was up at 6:30am today, after charging all night it was at 100%, here it is 9:18am, my usage is at oops, well I already did the reset so it wont show my usage until next full charge, but I am at 66% already! Its never that low by this time! I usually work at 9:30-1:30 and by 9:30 normally my phone is still in the 90's.  Last night regular usage, and actually because it was Sunday less usuage than normal, it was at 10% last night when I went to bed. I think having this phone for 3 years (3Gs) its only gotten that low maybe 2 or 3 times, and having left it in the car yesterday for most of the day, standby only time, for it to drain that low is crazy to me.
