[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] aejazhaq:
Hello forum:

Im a doctor resident in training so i dont know a lot of the technical language you would use...I'd really appriciate it if someone could help me wiht my wakelocks....ive almost given up and if this forum doesnt solve it im throwing it away...

I have a S3 i9305 LTE...just rooted it the rest it all stock, ROM and kernal (JB 4.1.2 on BLL5)

I had this MASSIVE battery drain by the fastdormancy but i solved that by rooting and installing the toogle switch for i9300 (works for the i9305 too mercifully) so solved that....just as i heived a sigh of relief then crops up the

1) audioOut_2 wakelock

2) GTALK_ASYNC_CONN_com.google.android.gsf.gtalkservi ce.AndroidEndpoint wakelock

3) PowerManagerService

4) mdm_hsic_pm0

5) RILS

thats what the BBS says...and on the side if somebody could help me with the scroll lag as well. surprising that this phone has mosr power than the combine used to send man to the moon and it cant scroll smoothly! samsung is an utter nut-head for making phones that aren't useable for the common guy.

this is really a HUGE problem for me cause i get calls at all hours of the day. I went home after 30h shift and fell asleep on the couch. i had about 50% batt so i though i had enough and my battery dies somewhere in the heavenly sleep i was in...my prof kept calling me and i missed out on a surgery and he was absolutly mental with me (not that i blame him)...so you see I cant have this happening to me again. Im forced to carry the charger around everywhere i go and its a matter of time before i lose my phone leaving it around. Please help and be simple.

contingent to helping, everyone is a hero!

EDIT: So heres what ive been able to work out so far...

i flashed varioud ROMs and not all are the same...my suggestion is to try different ROMs and especially of your in a bad connection area and have sync wakelocks my advice is flash a different kernel (list of i9305 compatible kernels available here: http://xdaforums.com/showthread.php?t=2206898 goto the baseband/modem section). in my case my stock modem was LLB5 and it was horrible...i flashed BMD1 and i get full signals all over the hospital! this should help reduce the sync wakelocks esp like google's to a good degree...just remember not all modems and kernels work for everyone...thats just a hit and miss...you'll have to figure that out on your own....one phone may vary from the other...

The other thing esp if your phone heats up a lot on the most trivial tasks i highly recomment flashing a different kernel....again the list is available in the same post linked earlier...i had persues 36.2 work a bit esp with undervolting but not where i wanted it to be...so my plesent surprise i flashed the latest stock kernel and i dont even get the slightest bit of warmth anymore! that was a big surprise since i was told over and over that a quadcore will always heat up.

as for the battery try different ROMs...im currently using X-power by smaberg....it lasts me about a day and a half with approx 6h of screen time...i dont use it for gaming so you might have a varied preformace.

I doubt some wakelocks eg the audioout_2 wakelock cause the wake times dont add up with the audioout_2 lock....they do if you exclude it....like wise the download manager wakelock is the same thing, somehting is downloading in the background like a fix etc....

I'll keep posting if i make more breakthroughs....

EDIT:

FASTDORMANCY wakelock:

Im going to keep this short; fast_dormancy is for 3G only (maybe also lte) and its some over the top thing. more info by erica griffin on youtube. suffice it to say that if you install fastdormancy toggle by gokhanmohal from the app store you can easily switch it off. works for the i9305 as well. requires root.
