Re: ARC/ARC S Battery drain problem Solved Finally !!!!!

Results after using the Kernel

  • This is what i got after 16 hours of use, 20% of battery left.
  • App used, Video player, Pdf Reader, Asphalt 6 HD, Quick Office, Market, Music and few more.

***The most IMPORTANT thing is, that the display was on for 5 hours @ 35-40% brightness level. This is a gain for me, With the earlier kernel, i used to get maximum 3hours of display time, with the same amount brightness level set.***

Another Benchmark is here. Please find this thread.

In this thread I have tested ARC S HD video playback capability. And the result was 300 mins playback with fully charged battery.

Now, with the new kernel, ARC S gave me 354 mins of HD video playback.:smileyhappy:

That's another good find for me.

Still results may be not same for all. Actually I am getting better battery back up, so I shared.

Re: ARC/ARC S Battery drain problem Solved Finally !!!!!

** My Kernel is also the same, even after i tried the above process. But as I mentioned above, that i am seeing changes in battery life.

*** Model No. LT18i to LT15i should not be changed if you do the process correctly. :smileyconfused:

This is the screenshots of my device

Yes or No? if you say yes, i ask to Close notification update? but You say No ,then What should i do:smileyconfused:? i should Update Software on Sony Ericsson PC Companion 2.0,right? and the last question i suspect "Kernel version" = "Phone Software Version",right ?

Re: ARC/ARC S Battery drain problem Solved Finally !!!!!

No. 1: The phone is asking for an update because you are using an old "KERNEL". If you update now, it will revert back your kernel version 0.58 stock. So again the battery drain problem might occur. Your firmware version is 0.58, so it's fine, do not worry about the kernel.

So it is upto you, using an old kernel won't affect your phone function.

No. 2: After pressing this *#*#7378423#*#* check model info and if it says LT18i, then it should be fine.

No. 3: If you want the latest firmware update 0.62, then it is mentioned above @ uliwooly-wooly post.

Here's the link again.

http://talk.sonyericsson.com/thread/29197

The update process is well explained there. Please check.

No. 4: The latest update of 0.62 firmware may not be able to combined with the old kernel. It didn't worked for me. So I stick with the old kernel.

**** I have checked, the above kernel combination trick works only with 0.42/0.58 firmware version now.
