    Hello, guys! My girlfriend is getting horrible battery life with her iPhone 4S. I can stand the horrible performance, but battery life is important. She can't go through 4 hours of usage. Thanks a lot.

    PS: background refresh disabled. Mails on manual and push. Automatic brightness.

    The only thing I can think of that the battery is 'death' you could also try to re-install iOS..

    Btw if she hasn't upgraded to 8.3 check battery life with iBackupbot (for Mac & PC)

    The 4S was the worst iPhone in terms of battery life. Not really much you can do.

    The apps she is using are typically battery hogs. So unless she is willing to stop using them (which is dumb because it is a smartphone) there really isn't too much you can do.

    On my 4S I get slightly better battery life because I don't play games like Candy Crush. I'm sure it would be about the same if I did.

    Basically it's Apple's way of saying... please upgrade me to iPhone 6.

    Replace the battery then.

    It isn't very hard to do it yourself, and you can easily get a kit online with the required tools (00 phillips and a pentalobe driver for the screws on the bottom).

    I've done them for $8 battery only, and you should be able to find a kit for around $20 from what I've seen.

    Night and day difference. I've still got a 4s that I use as a spare device running iOS 8.3. It will easily go 6 hours of usage and last throughout a normal day (7:00 to 11:00 generally) with a bit left over. Usage for me being iMessage, Facebook, Instagram, decent bit of Camera use, Safari, Notes, Mail, Evernote, Music, Calendar, Weather apps, some YouTube, and the occasional game.

    Other than that, you've probably disabled most the battery hogs, screen brightness, BT/WiFi when not in use, background app refresh (minimal), reduce transparency (helps with the lag/jitteriness) and perhaps a few smaller things.

    But I'd go for a new battery either DIY, or find a shop. A local one in my city will do battery replacements for $30 on the spot.

    This iPhone 4s has been refurbished by Apple a few months ago, so it has a new battery.

    Battery Life with iPhone 5

    I was having the same issues on my iPhone 5 with iOS 8.1.2. Upgraded to 8.1.3 and it seems to be pretty stable. Way better than the previous couple upgrades.

    But now current iOS is at 8.3 and I'm just not sure I really need to update it. I'll get a new iPhone with next release in Sept/Oct and sell this one.

    Anyone with thoughts on upgrading a 5 past 8.1.3?

    My iPhone 5 runs iOS 8.3 and it's a major improvement over 8.1 in terms of performance.

    Same here. I am an experienced and qualified electronics engineer, and have recently replaced the battery myself with one from a VERIFIED supplier with only 1 charge cycle from new... same problems, LOW battery, and crashes out very often at ~ 20%. I am not able to pin it down to any one thing, nor are Apple.

    meh, I'll just buy a 5S or 6 :)

    The 4S has such a low capacity battery for today's popular apps (which are naturally battery-drainers) that the only way to boost capacity is to upgrade to a 5(C), 5S or a 6. Also, it's very slow with iOS 8 anyway.

    My iPhone 5 had terrible battery life. It was ok out of the box with iOS6 but as soon as I installed iOS7 it instantly became lousy and remained that way throughout the numerous subsequent updates. So I can fully appreciate that the 4S has become equally lousy with iOS8.

    Same. Apple should stop to destroy the old phones... that's not fair.

    My 3 months old battery seems worst too on my iPhone 4s. Here is my battery live.

    Sorry to say but that's kinda normal for a 4s, the only iOS device that does worse is probably the 3GS. I have around 5~6 hours up to 8 if I'm just watching videos.

    I mean the page where statistics of usage are displayed (too see how much you used your phone with one charge).

    Why? Does this not work anymore on 8.3?

    I still have an old iPod touch. Just like the old iPhones without the phone. At some point, with a new OS, the battery would be in constant drainage mode so that after a couple of days, it would all be gone. And all the while I would not even use the thing. Useless now. I suppose it doesn't matter since I use the 6 Plus now.

    Well, that's not a good result (3 hours of usage). You even plugged your phone in!
