Tip for Low battery drain for ARC ..... - Xperia Arc Themes and Apps

Hello guys
Today i am going to give you a very small tip may you people like it ....
i used 2.3.4_283 firmware in Arc for a long time , after that i flashed 42 firmware and feel that its drain battery fast as compare to 283 firmware either you are using you phone or it is in deep sleep mod
Then i flashed 58 firmware and after that 62 firmware but battery drains still fast
then i try one thing on my arc i get the Kernel from 283 firmware and flashed it on all three version of firmwares ( 42, 58, 62 ) and notice that the issue of fast battery drain is solved it is only because of 283 kernel
now i am using 42 firmware with baseband 64 and kernel from 283 firmware

It does'n matter what ever the firmware you are using or what ever the baseband you are using ....... you need to use kernel from 283 firmware only for low battery drains ..............

MY Recommendation
you can use any firmware but only use 283 kernel with baseband from (42 or 58) only

i attached kernel from global generic wold 283 firmware also...
How to flash different Kernels
1) connect your phone into fast boot
2) open cmd
3) fastboot devices
(write this command and enter it to check your phone is connected in
fastboot or not)
4) then write this and enter
fastboot flash boot kernel.sin
Done ..........
remember to copy kernel .sin file in that folder from where you are going to launch cmd

mate, that's a good idea, but you should mention that you can just flash the kernel by excluding the baseband and the system in flashtool
anyways i tried that 10 minutes ago and it ****in works ! thanks alot

you can flash the kernel.sin alone through fast boot mod

Doesn't work for me . Boot loop. Tried both .283 and .368 firmware kernels. (BB -36)

How about the battery life compared to the OC kernels?

Battery life is always better on stock kernel, without OC.

Thanks a lot dude. It genuinely works. Thanks a lot.

I use the last .62 firmware with 64 baseband and no more drain battery. Today i use 12% of battery instead 45% for the same use of the telephon. I will install the 283 kernel for to do a test.

---

is the 2.6.32.9-perf kernel the one from .283? cos this kernel came with .42 when i flashed .42. Do the two have different version numbers?

In every stock rom the stock kernel have the same name like in 283, 42, 58, 62 firmwares
but only the name is same not the kernel

---

Now I m flashing.Tomorrow I will see if are any changes.

---

Update
After i've done this, my phone says that there is a new update. And that i have to upgrade.
Should i do this? I'm guessing that an upgrade will change the kernel back to what it was.

Brilliant, cheers mate

Today with 283 kernel, i used 20% of battery with the same use. Less better than the 62 for me. I continue the test for 3 charges of battery.

---

Works great. Thanks.
Btw, after reverting to stock kernel, wifi does not work anymore.
I cannot turn it on, it only shows 'Error'
I used doomkernel v15 before, do I need something like wifi patch just like the procedure of flashing doomkernel?
EDIT: Got it working. Flashed the stock modules and worked.

yes you are right
after flash the 283 kernel our mobile give us notification of new update available. but its not the new software this notification is come because we are using old kernel . you are already using the newly firmware so no need to update it again
but
if you update it again it will flash the whole rom again with kernel also....

The result is revers for me mate
i am using 62 firmware now with 62 kernel from 2 days
and i think the battery drains is quicker as compare with this combination describe below
42 firmware with 42 baseband and kernel from 283 rom

baseband from 62 firmware did not giving the best result with 283 kernel
only 42 & 58 baseband gives the best battery life & low drain with 283 kernel

xperia neo user
can i do this on xperia neo ?

May not be the case for everyone, but i am using .42 firmware with .36 baseband and kernel from .283 and my battery drain is amazing. 2 days, 10hours, 5minutes and still 54% battery remaining after average use.
hope this helps someone else
brezzz
