[Q] Rooting Other's Phones / GB Update

My Mom recently got the G2X per my advice, and is complaining about the battery. I can root her device, freeze bloatware, install juicedefender/setcpu, but since she lives out of town, I'm afraid if she wants to exchange the device, it would be difficult to talk her through the unrooting steps.
Should I wait for the GB update and hope the battery gets a major improvement w/o needing to root, or go ahead and root it?

One fix you could have your mom try is setting the network preference to WCDMA ONLY. If she is in an area that has good/great 4G coverage, she would not have to worry too much about it losing all bars and trying to reduce to 2G as it does by default when set to GSM/WCDMA AUTO.
It's goes against all logic because WCDMA ONLY (4G/3G only) should eat up more battery, but there seems to be some sort of bug that makes it conserve energy when not on auto and not trying to switch back and forth.
Again...maybe give it a try if she has good 4G coverage where she lives, works, plays etc. Since yesterday morning when I first tried this, my battery life went from an average of 5-6 hours, to an average of 12-14 hours. All with fairly heavy use of GPS, WIFI, Web, Calls etc.
Settings > Wireless & Networks > Mobile Networks > Network Mode > WCDMA ONLY. Reboot device....fingers crossed
Good Luck!!

Wait till GB is your best bet in that situation

I know I dont post on here often but ive had several android devices and this phone is the worst in battery life. Was getting 8 hours, max
What I did that helped was root the phone and inastalled setcpu and changed the default sync times of facebook weather bug e lite ect to two hours and finally I get a full days use. (16) hours or more I still have bluetooth wifi qnd gps on. I hope this helps.
Oh and I do toggle 4g / hspa and edge when I know I wont be around a charger this makes the battery last about 20 hours for me.

I'm assuming that's screen off correct?

I haven't rooted my phone neither have installed setcpu. I have installed only juice defender and I get more than a day of battery life. I used to get only 6 hours max before.

Set cpu manages the speed based on demand.
If your talking about battery time then its what I call moderate use of about 40 text and hour of talk time and glancing at engadget.mobile for a couple of minutes.
Not like today im using this thng like crazy and sitting at half battery now . Took off the charger ar 8 and its almost four now

Do you use SetCPU in conjunction with JuiceDefender, or should it be one or the other?

I am rooted but am running stock, I have juice defender installed and get a full day out of my battery. Unplug at 7am in the morning, moderate use during the day including games, txting, and gaming and then by the time i go to bed at around 11pm or so I am usually down to 20% or so. Juice defender is amazing. According to my battery stats I have been unplugged for 7hrs 27 mins and I am at 80%

Unfixable huge battery drain

Hey fellows s3 owners,
I have a huge battery drain problem when I'm at school. My battery plummets insanely. The signal isn't too good, but my battery stats show that the signal isnt the main issue. Its consistently either android os or android system draining it, I don't know what it is doing and have been through multiple s3s and no fix. All my friends have the same issue. I'm on stock unrooted and locked.The only thing to do is airplane mode it all day everyday and I really need signal to get through the day for obvious reasons. I need a fix to this issue, and it is a huge problem. ANY HELP WILL BE APPRECIATED GREATLY AND I WILL CONSIDER DONATIONS!:good:
Attached are screenshots from BBS and the stock battery stats in the settings
Thank you!

Don't see screen shots on tapatalk but if u r saying airplane mode fixes the battery drain then u already solved ur problem Cuz it sounds like the os is killing the battery trying to get a good signal so only way to fix is a) try flashing a different modem to get good signal at school or b) switch to a carrier that's gets service there

Search for modems for or device and flash a different one each day til u find one that gives u better service there should be a modems thread in ur device sub forum with instructions and u can ask there if anyone in or area using which to get best service but generally modems r a trail and error to see which works bestv

Do you keep it in 4g? If so use a app like phone info and throw it into 3g only and see how it does (cdma auto prl)

Severe Battery Drain Issues - Any Help?

Hey guys,
My M8 has severe battery drain issues. It went from 85 percent batter to about 25 percent in the course of 2 and 1/2 hours and all I've done is sent a few texts. It's been like this since I bought it two days ago, right out of the box. I've flashed Android Revolution Rom and that didnt help.

Settings, apps, running, and see what's running. Install wake lock detector and greenify. Let wake lock run a while and greenify the bad apps. You can also go into app permissions and deny a good many wakeups but you have to pick and choose cause you can prevent the app from working.
Also choose a governor other than interactive, like on demand and noop or sio for scheduler.
Also turn off WiFi and anything else if your not using it, location especially.
Good luck.
HTC One M8 powered by SinLess Audiophile v3.5.5/Elite Lunar 3.4.0

Could your other posts about converting to AT&T or needing a VZW radio zip have anything to do with this? If you flashed something incompatible, there is a pretty good chance that's causing your battery issue.
"I figured it out. For anyone else out there that has a Verizon M8 and are using it on AT&T, you can convert your phone to the AT&T variant. I'm getting LTE but not constantly, it switches between LTE and HSDPA but it's staying mostly on LTE. Yay!"
If your signal is bouncing around, that will kill your battery.

It was like that out of the box before any modifications actually. The first day I got it I charged it up and it drained to zero within about 4 hours. The second day same thing. I have to charge 3 times per day just to get through a whole day. And that was before I even rooted, did S-off, unlocked bootloader or flashed any roms. After having it for a couple of days I converted it to an international device to get lte (which I'm getting) and the battery is the same as before I did anything. No change. Drain drain drain. It also charges very slowly about 4 to 5 hours to go from zero to 100 percent. I've even tried turning the mobile data completely off and connecting to my wifi at home and even with mobile data completely off it drains the exact same. I think my unit is defective.

If it did that from the beginning, I would bet on a hardware issue. I don't get battery life that bad even with heavy internet use and streaming on WiFi.

Thanks. I ended up exchanging it for a new one and the new is fine. I get a full day with heavy use. Yeah the other one it was really crazy. I would have to charge 3 times a day, it was insane.

[Q] Is it possible to turn of Volte?

Looking to hopefully fix this cell standby battery drain. Is it possible to turn off volte on Verizon S6?
thanks

Settings then advanced calling.
Turning it off will not help. This is a known issue.
What has worked for me is turning advanced calling off, wiped cache, turned advanced calling back on.
One time I forgot to turn volte back on and I still had the drain until I turned it on.
Let me know your results. I had to get a replacement because nothing stopped the drain on my first s6
Sent from my SM-G920V using Tapatalk

So I followed your advice for advanced calling and my phone is at 95% and cell standby shows 1%. Is this good?

Give it a day and post your battery stats with info on how long you were on wifi. Way too small of a sample size here to determine
Sent from my SM-G920V using Tapatalk

Will do. But where can I get the WiFi stats?
Sent from my SM-G920V using Tapatalk

That's just your estimate.
Ex: out of my total 24 hours I was on wifi for about 20.
I don't know if there's a way to know exactly how long you were connected to wifi unless you turn it off every time you leave where you are on wifi.
Sent from my SM-G920V using Tapatalk

So I my phones at 14% are 7hrs 16mins on battery. I was on wifi probably about 75% of the time. my cell standby is at 15%. Stats in the screen show.
Is this bad?

For reference... Almost 100% WiFi today, 50% left battery power.. Mostly phone calls today, and doing some reference look ups. I don't play games on my phone.

Having cell standby at 15% on mine. Is that to high? I was doing a lot of data transfer today over wifi. Coping files to my google drive.

Yes your standby is too high. Have you done the workaround? Also what was your sot
Here's what I've been getting
Sent from my SM-G920V using Tapatalk

When you say workaround, do you mean wipe cache then turn on advanced calling.? I've done that and also factory reset and then the advanced calling again.
Anything else to try.
thanks

Time for a replacement device
Sent from my SM-G920V using Tapatalk

Bummer. So does the cell standby increase usually when on wifi most of the time?
Also, I;m rooted and I know I need to unroot before going to version, but should I unroot before calling thier tech support?

Most people experience it while on wifi. Some people have reported they still get the drain while not on wifi.
I never call tech support. I always walk into a corporate store. On this occasion I said I have terrible battery drain. Told them quickly it was before and after the OTA, tried a couple workarounds I found on xda. No questions asked and they ordered my replacement. Took him longer to make a minor account change (changed first name from David to Dave) than the replacement process took.

sounds good. I'll flash back to stock and head to verizon.

Are folks with the cell standby issue that return the phone for a new one, not seeing the issue. I guess it's a crap shoot if you get one that doesn't have the issue....right?
Just wondering if this will ever be resolved.
thanks again

HORRIBLE battery life after November 16 update.

Hey all
I have a Sprint Galaxy S 6 that I just updated with an update that claimed to be to improve "battery drain".
It is losing 13% in a half hour without using the phone.
I have no apps running.
I go to settings and it seems that Google Play services is always the one that uses most of the battery.
I never got great battery life but this update seemed to make it worse.
Am I missing something big???
Any advise would be appreciated.

Probably your phone won't go into deepsleep. This is caused by wakelocks and alarms. You can fix this by rooting your phone and install powernap or factory resetting your phone & start all over again.

I would rather not root my phone... I did it with my last three phones and was more trouble than it was worth for me. The phone has all of the features that I like and I don't have a need to flash ROMS.
Any other suggestions?

In that case factory reset your phone, this will delete all of your apps and data so also the wakelocks and alarms. From then your phone will go into deepsleep and you won't lose so much juice when you don't use the phone

Hi, I'm also having battery life issues. I've factory formatted from recovery menu, but I still get battery issues. I charge my phone about 3 times a day and I don't have any significant drain according to the battery usage settings.

The same here. I have everything okay according to battery stats. But I lose like 5-8% an hour when screen doesn't work. Don't know what to do.

I basically surf the net and use WhatsApp. By early afternoon, I'm down to 60% battery. I unplug my charger at 6am everyday.
