A few people have been saying that their iPhone 4S battery dies fairly quickly after charge, a good way to ensure the battery doesn't die as fast is to change the brightness, not enabling as locations finders for apps e.g. iMaps, Facebook, Dominos Pizza etc.. Also maybe change the amount of times Notifications remind you, instead of every 1-2 minutes, maybe once or twice.
Also try wiping your phone, and see if this improve your battery life. If any of the above don't have any affect, I'd consider taking your iPhone 4S over to your nearest Apple store for some further advice or maybe a battery replacement.
Hope all of the above help in some sort of way.
I'm recently noticing something weird about my iPhone battery: when it reaches the last 25% it makes sudden drops! It was 24% then I made a one minute call and as I hund up, it suddenly dropped to 17%. It did the same thing last week and dropped from 22% to 11% just as I unlocked the phone!
I'm using iPhone 4 running iOS 5.1.1 not jail broken. I always shut the apps after using them andont have anything running in the background. I had the phone since November 2010 and hate to think that the battery is faulty in less than 2 years. Anyone has any explaination???
yes i do, i had the same issue with 5.1.1. their is a glitch with the software. a way to check is:
settings<general<usage< go down the the bottem, if your standby and usage time are the same, u have the glitch.
you will have to restore your iphone and DONT BACK UP! if you do, the glitch will be put back on. set up as new!
I went to apple genuis bar twice with this issue.
I hope this worked!
I'm facing the same sort of issue
Yesterday when battery drops to 26%, I unlock the phone and suddenly the battery percentage change to 16%.
I checked the usage but usage was same as it was at 26.
Also some times the battery percentage stays on certain number for a long time. Like today it was 71% since 8 hours of standby and 1 hour of usage.
Is this a software glitch or battery issue?
Well, Sorry I didnt understood your last post.
I mean Standy and usage remains at same levels. I just unlocked my phone and the battery percentage drops 3 % instantly.
Usage: 6 hours 21 mins
Standy : 13 hours 10 mins.
These figures remains same as after the sudden drop.?
Is this a battery issue or should i need to reinstall IOS and set up as new. Thank you!
Here is an update over battery draining
What I notice is as follows
My iphone 4 has iOS 6 installed.
It's battery drain 1% every 3-4 mins over wifi and 3G
If I switch off wifi and cut off cellular service, the phone is in airplane mode. At this point still the battery drains at 3-4 mins.
That's weird. No change in draining whether cellular and wifi is ON or OFF.
Any suggestions ?
