Battery life is starting to piss me off.

[RRutter]

I thought iPhone 5 has the new A6 chip? I don't think iPhone 5 has the A5 (4S)

According to http://www.apple.com/iphone/compare-iphones/ iphone 5 is A6, not A5.

You're right. I'm dumb. Edited

can someone help

if anyone can help I would really appreciate it.
I monitored my usage today in the office and here are the stats.

Time - Usage - %

10:36a - 1hr42min - 76%
11:36a - 1hr54min - 73%
12:44p - 2hr33min - 62%
1:17p - 2hr45min - 59%
2:36p - 3hrs - 54%
3:32p - 3hrs26min - 43%

This is with LTE and WiFi on, locations off, auto brightness. All I used the phone for was light texting, checked two voicemails and majority during lunch with news apps, sports, etc.

the most notable drop was from 2:36 - 3:32pm where I only used it for 26 minutes and dropped 11%.

Please tell me exactly what you all mean by resetting. Do I have to reset to factory and NOT restore after? as in re-install everything and lose all my texts, etc?

also, my office location has piss poor service, often switching from "No Service" to one bar, two if i'm lucky. the work WiFi certainly does not help because I have to reselect the connection to get back on, and everytime I put the phone to sleep it logs me off the connection.

Is THAT the main reason why my battery is getting sucked? I sure hope so.

I got this tip off of another forum here, it might work for you. I restored my new iPhone 5 from a backup of my iPhone 4S. After two weeks, I noticed that I wasn't really noticing a huge improvement in battery life -- the phone was basically on the same charging schedule as my 4S.

I read a thread here that said the battery charge settings have been known to carry over from the backup of a previous phone model to the new phone, and that the poster had seen a dramatic increase in battery life after he did a "Reset All Settings" on his phone. I figured it couldn't hurt, so I tried it (about two hours ago).

Before the reset, my phone would drop 2% from 100 to 98 within a few minutes of being removed from the charger. Since I reset the phone a few hours ago, the phone didn't hit 98% until after about an hour of moderate use (downloaded a 50 minute podcast, listened to the whole thing, checked facebook compulsively every 10 minutes or so, sent/received about 20 text messages, synced about 1500 emails).

Obviously I won't know what the full improvement will be til I run out the battery, but initial impression is the reset all settings has helped improve battery life. It only took about 5 minutes to reset all of my settings (wallpaper, alerts, privacy, permissions, etc...) to what they were before the reset, so I wasn't too concerned about that minor inconvenience.

Yes - definitely try the reset. I have awful service at work - like either no service or one bar and then Edge in and out for data. I'm sitting here (now at home with excellent service) with still 46% left on my battery. My usage is at 3 hours and 12 minutes and standby 1 day and 11 hours. I bet I can go another full day. I took it off the charger on Tuesday morning at 6 AM. On Monday at 6 AM I took it off the charger and barely made it through the work day. Had it back on the charger at 6 PM. So right now I would say my battery life has improved over 300% since the reset. Go for the reset, if it doesn't help, it won't hurt. For me it has been incredible.

1-3 bars of LTE at home and I can't top 5.5 hours usage. Light usage at that. Seems that I should still get more based on what others report but I'm still not sure. Thought 5-5.5 was normal until today when I had full service and watched battery drop just as If I had 1 bar and would have maybe gotten 5 hours usage at that rate.

Im using 3G and i can basically watch My battery drop.. 68% then 4 minutes after i got 67...

If your battery life dropped 1% every 4 minutes then that would be 400 minutes of usage. thats 6 hours and 40 minutes of usage.

thats NORMAL.

My first replacement iPhone had poor battery compared to my initial i5 and my current replacement. Fortunately that one had a scuff as well so I had no problem exchanging it.. Good luck

It's starting to piss me off too.

With the following conditions:
- 3G only, always 4/5 bars
- Bluetooth disabled
- 1 Gmail Push (exchange)
- Location services disabled
- notification mostly disabled (only facebook, whatsapp, and mail)
- icloud disabled
- fixed brightness to 30%
- set up as new. Reset done, calibration done (1 time)

It lasts me 5.5 hours of light use (mostly browsing, no streaming, no 3d or graphic intensive games) and 23 hours stand by. In 7 hours stanby (no notifications) it draws 8-9%.


It's really starting to piss me off too my IP 4 after 2 years and under the same conditions lasts 2 to 3 hours of usage more!

I returned my iPhone 5 for a SWAP this morning... I will receive a new unit in the next days. I hope it'll be better.

Exchange it -- I get 9 hours usage and 16 hours stand by before going to Zero... I will post it again once I get my replacement later today.
