I have recently bought a new iphone 4s- 16gb. Updated it to 5.1.1 version.
The iphone has major battery issues. I charged one night and morning it was drained. It was only on wifi.
Also, while on wifi - the battery drain is too much. The standby time and the usage time are generally same.
- Location was off
- wifi on
- Emails on
The drain is very fast.
Next - the apps like facebook, contacts, watsapp etc carshes quite frequently.
I installed an app called 'Battery Doctor', in the stats i found that the CPU usage is very high even wiht only 1 app running.
similar is the case for RAM usage.
Would require help from someone to help me.
I have even tried Restore but the conditions still exist.
If it's new; did you restore from a backup of your old device, with pictures and videos and have now enabled iCloud with backup? If so; you iPhone may have been backing up over the wifi.
The CPU and RAM usage seems strange though.
I would consider backing up the device and restoring it to factory and testing it from a blank setup just in case.
Since 5.1.1 I've noticed no change in battery use pattern
Also worth defining what very fast is. As my battery drains I normally have 8hrs usage and 28 to 40 hours standby on the stats.
I am having the issue...only I suppose a bit more serious, since I simply cannot use any apps nomore...they crash literally seconds after opened. There is not enough time even to reply a message on Whatsapp.
I have thousands (not exaggerating) of Low Memory diagnostic messages, each related to a crash.
I have seen the meesages related to dataaccessd...and it does make sence, since the memory just drains completly.
The battery lasts no more than 5 hours on wifi, with absolutely no apps opened.
I have downloaded an app for checking the memory..and well...it is amazing how it goes from 320...to 0 in a matter of seconds with nothing opened at all.
Please see my post. And please....someone help me out.
