Problem: very weak battery, even for the diamond!

[wedge210483]

Hello guys!

It's nearlly my first posting here, but i'm reading this forum for quite a while now.

I finally got an Xda diamond and everything was ok the first couple of days, even the battery was satisfying. When i use it really much, the battery lasts for about a day, that's ok. But 2 days ago, suddenly the battery got empty from 100% down to 0% in 7 hours, although i did not use the phone much. I had a call for about an hour and that's it.

Knowing there are some possibilities to save energy, i followed some advice from this forum:

- took down the display light to stage 2
- switched off UMTS
- switched off GPS
- installed powermanagement.cab
- switched off RSS Hub auto-download
- made sure there are no applications running in the background all day
- made sure there are no data-connections like Bluetooth or GPRS running all day

I also installed PowerGuard v1.2 which told me, my Diamond drains about 65 mA, what seems to be a proper value, comparing to other peoples around here.

This morning i took the Diamond off the charging cable at 8:00 and it switched off at 16:00. I only used it for a 1 hour phone call again, thats all. I did not do anything else with it.

I don't unterstand, why it lasted much longer the first couple of days. Anybody have an idea?


Thx so far!

1. Check with Task Manager Cpu proccess
2. Hard Restet ?

I have the same problem AND additionally sudden softresets.
The battery is defect. I will buy a new one and o2 will refund the money.

The battery is not supposed to get empty to anywhere near 0%, it can be damaged if it does. The phone is supposed to turn off to prevent that happening. :confused:

If killing tasks does not help, maybe you just got a bad battery? Edit: ^^^ What he said!

Hi!

I recently found the solution. My sim-card was too old! I had been using it for about 4 years. A couple of days ago, I ordered a new one from my provider (O2 Germany) for free. Since I changed the sim-card, I never had any problems with the battery anymore.

Why didn't I find this advice anywhere? :confused:


Cheers

Your SIM card was "too old"? My technical prowess is nothing to brag about, but even I can tell you that that could hardly have been the cause.

Older Sims seem to drain more battery power...

I have to agree with H3x ... I don't see how a SIM card would have any effect on battery life.

As a point of reference, I'm very satisfied with my battery life. I charge it for an hour or two a couple times a week. I am diligent about turning off WiFi, Bluetooth, and running apps when not in use, but other than that I don't do anything special.

With GSM band manually selected in phone options and moderate use, my diamond can last over 2 days, with "auto" band selection it barely lasts a day...it just drains stock battery so much, even in standby...but I still can't be happier with my device, no matter what ;)
Decided to watch battery more carefully over PowerGuard, some things started to make more sense...

Yeah, I have that selected too, so I'm sure that helps. Maybe the OP should try it?
