[Samsung Galaxy Ace Plus S7500] Amirstars:
Hi,

One of the most common issues in CM 10.1 and CM 10.2 is the battery fast drain In addition to the usb slow charge.

I searched in more than one place for solutions to this problem, But most of these solutions led to the failure and did not succeed.

Today i discovered the cause of the problem.

It was mostly the Mobile operator :confused:

I do not know if anyone would have discovered this before.

So this is what i did

For the battery issue:

in my older stock rom GB.

i used the DU Battery Saver app https://play.google.com/store/apps/details?id=com.dianxinos.dxbs To determine the remaining time of my battery life.

It was mostly 25:00hs When fully charged

After i flashed CM 10.2 and using the same app (DU BS)

The time life was about 18:50Hs. fully charge.

After several attempts, I discovered that when turn on the airplane mod,

The time life of the battery is increasing Between 25:00 and 24:50, even the WiFi ,the Bluetooth, sync and location access is turned on.

Of course i don't have any idea how to solve this problem :) i just share what i discovered, hoping that someone, someday give us a solution.

and again i do not know if there is someone discovered that before or not.

New ideas?!!

For the usb slow charge issue:

1.Simply plug in your usb cable to your phone.

2.Reboot.

That's it your usb cable charge you device.

OR-----------------[update 27/01/2014]

Use a USB cable that support charge only " the usb cable which come with the mobile pack is designed to transfer data and power charge" i don't know why there is conflict/relation between trf.data and charging. or it's just a sittings in the CM

I use a cable came with a power tank, when i connect the cable to my laptop / pc the laptop doesn't sense the mobile and the mobile charge perfectly.

i use this tank power:

Please, try and give us your experiences for the benefit for all of us.
