[Nexus S Q&A, Help & Troubleshooting] lvnatic:
I'm surprised that after so much time since android has been released, people still don't know how the built in battery monitor works. The percentage shown there equals 100% if you add all of them. That shows the total energy that the phone uses and displays which apps consume it and how much of it. If it displays 100% for the android OS (let's just say, that it would display only this), it means that the only thing which consumes energy on your phone is the OS, nothing else. That doesn't mean that the battery usage is 100%, it would killl the phone in a few seconds from full charge.

So if you had 53% for the display before applying the live wallpaper and 46% after, it means that there is a new process in the phone that eats voltage.

Those values show what uses the most energy from your current total usage, it doesn't mean that the display eats 46% of your battery. The live wallpaper probably has 15% or so, but it has a much bigger impact on the battery then 15%.
[Nexus S Q&A, Help & Troubleshooting] Stothex:
Hi,

just a question just on that topic:

I got the I9023 with SLCD and i want to optimize my battery life.

What is a good % of power usage for the display? Mine is 54% and i think it's quite high, is it normal?

Is there anything i can do? I just got the phone 2 days ago, so i'm using it more often than usally (well it's new, i'm not familiar with android.) but in a week or so, when i'm used to the phone, i want to get the maximum battery life out of it.

Data:

Android 2.3.6

I9023XXKF1

Kernel

2.6.35.7-gf5f63ef

Android-build@apa281 #1

Build Nr.

GRK39F

If anyone knows, how i can get a better battery life and overall performance, pls tell me, i really don't know where to start, i just downloaded the most common apps i needed, or wanted to use and used go launcher ex to get the touchwiz 4 theme on the phone, as i am more familiar with that (i had bada system before, hated it (well atleast i liked touchwiz :D)

Thanks a lot in advance guys!

im running cm7 what kernel would u guys recommend i need battery life stability and speed
[Vibrant Q&A, Help & Troubleshooting] crazy25000:
I'm running cm7 also and I recommend using nightly 26 and use neo7 kernel. You will get amazing battery life while being over clocked, plus it's stable.

I've flashed all the nightly builds and 26 has been the best one.

Then flash the neo7 kernel from the link below. If you use this kernel with the new builds, you will not get good results.

Be sure to flash the kernel cleaning script before flashing a new kernel and it's on the link.

Hi, i'm new android user on HD2 and i've got annoying problem. My phone turns off during phone call, now i know it's caused by my proximity sensor. I was searching for a way to fix it without any apps, changing some thing in my phone. I found something in Dev Tools > Show Permissions. There you can find that phone is allowed to turn off/on device and disable keyguard. Is there possibility to don't let them be allowed to do these things? And can it help to disable turn off phone during call? Sorry for my bad language skills btw :P

Thanks for help!

I've been looking at apps but none of them tell me the Original charge capacity vs the current wear level (current charge capacity).

Thanks
[Optimus One, P500, V Q&A, Help & Troubleshooting] gkarthik16:
Try "Battery Calibration" from the market. It will clear out your old battery stats and shows you the correct battery charge. Follow these steps:

1. Download and install "Battery Calibration"

2. Charge your phone to 100%

3. Without unplugging, press the "Calibrate" button in the app

4. After calibrating is done, unplug the phone

5. Use the phone till it drains out to 0% and turns off

6. Charge it to 100% without a break

Now your phone should show you the correct battery stats. This app is a must-have if you've flashed a new ROM onto your phone. But you can use it to calibrate your battery whenever you feel that it is not reflecting the correct charge.
[Optimus One, P500, V Q&A, Help & Troubleshooting] jan.petras:
Or if you have CWM recovery installed, just boot into recovery and wipe the battery stats when ur battery is at 100% and still plugged in.
[Optimus One, P500, V Q&A, Help & Troubleshooting] doktornotor:
People.... he is NOT asking about the calibration nonsense (pure placebo, the apps do not do anything useful). He wants to know the nominal vs. current capacity, i.e. the wear level.

@OP: Sorry, neither do I. Maybe the info is just not accessible by SW.
[Optimus One, P500, V Q&A, Help & Troubleshooting] jan.petras:

Battery charging and wear levelling

Actually, it is hard to tell the battery charging and weal levelling. It may vary due to the usage, temperature, environment variables (humidity etc) and the ROM too.

I don't that there is such applications available in market.

Google play only lists the apps which is showing the battery charged/remaining percentage only.
[Optimus One, P500, V Q&A, Help & Troubleshooting] Junior Einstein:
Usually batteries last for around 400-500 charge cycles. A charge cycle is completed when you discharge the phone to 0% and charge it to 100%. If you charge your phone once everyday, your battery will last around a year and a half I.e. 18 months.If you charge your phone twice everyday, the battery will last for around 9 months and so on
[Optimus One, P500, V Q&A, Help & Troubleshooting] allenwalker1998:

[Optimus One, P500, V Q&A, Help & Troubleshooting] Renzy1973:
gonna call bull on these numbers - I've had my phone for near 3 years. There's times it gets charged 3 times a day when being used heavily and times it can go 48 hours or longer before it needs to be charged. I have not noted any decrease in the time it holds a charge. I think there are too many factors that can impact battery life to say there is a set number of charging cycles it can handle.

Which means unless you had something installed to measure the battery right from the first charge you aren't going to find an app that can tell you what you want as there is no way for it to go back in time and tell you what the original numbers were.

BUMP

I would also like to know how much wear my battery has.

I had a DROID 3 and I had terrible battery life and when I replaced the battery the phone ran like new, it was great. In that case I was sure the battery was old at that point so now I want to know if I should do the same for my DROID 4 however the process is definitely more involved so I wanted to know if it was possible beforehand to see if it is worth it
[Optimus One, P500, V Q&A, Help & Troubleshooting] Faenad:
Bump!

There is a plethora of such programs for windows, like this one :

http://batterycare.net/en/images.html

we are looking for the same thing for Android

It would be especially useful since some battery will last longer then others...

Some battery will still have 85% of their design capacity after 900 cycles..

Others are at 50% after 300 cycles.. a 3000 mAh battery is now a 1500mAh one...

Depends fron the battery cell origin and quality.. japanese cell are the best

Also very useful to check if the replacement battery you purchased is holding the advertised charge...

Is it even possible to get that info out from a cellular battery?? They are much smaller, perhaps they dont have the required circuitry.
[Optimus One, P500, V Q&A, Help & Troubleshooting] tintinlibre:

[Galaxy Tab Q&A, Help & Troubleshooting] UncleScotty:
Hello, all,

About four of five days ago I upgraded by Tab's firmware via Kies. Now the 3G data connection is painfully slow. I connect via Wind in Italy. Here are some other details:

Firmware version: 2.2

Baseband version: P1000XXJMF

Kernel version: 2.6.32.9

Build number: FROYO.XXJMG

Does anyone have any idea how I can fix this?

Should I consider changing it to an unofficial ROM or a Gingerbread ROM?

I hadn't connected to Kies for a long time because I didn't have too many problems I couldn't live with.

Thanks in advance!

And yes, I did search for this problem but couldn't find anything particular to my circumstances.

Scotty
[Galaxy Tab Q&A, Help & Troubleshooting] rangercaptain:
Wind is t-mobile frequencies. What modem (baseband) did you have before the upgrade?
[Galaxy Tab Q&A, Help & Troubleshooting] UncleScotty:
I don't know. I've never upgraded the firmware and bought this here in Italy when it first came out last October, if that tells you anything.

[T-Mobile LG G2x] TechFu:
My Unrooted G2x had its first boot loop last night. I had bough the G2x directly from a Tmo store on April 20th. And two months later June 20th, i noticed my G2x rebooted and came up with “error checking”m or something like that. I put it back in my holster not thinking anything of it... a short time later, i realized my G2x was off an would not turn on. i put it on a charger and charged it for about a half an hour. When i tried to turn it on, it would not boot all the way. It got stuck at the LG logo and would keep rebooting. The only way to stop it was to do a battery pull. And every time i tried to turn it on, the same thing would happen. So i was forced to do a factory reset. Most of the other posts/threads i have seen that did this seemed to be rooted and have a non stock rom on it.

So my question is, would this be fixed in the update (yeah i know whenever that is) or should i ask for a replacement. Factory reset is such a pain. Putting everything back, recreating email signatures etc... And i am sure they will just give me a used G2x anyway. For the most part i had issues the first few weeks and mostly no other issues besides the battery life. Juice defener helps the battery life. And found fixes to my other issues. Well unless this keeps happening.

I was just wondering what others did,who had this experience. I was thinking of calling Tmo just so they have it on record that i complained about it, in case i need to replace it.

Thanks in advance for any advise offered--

Replace or wait until update???
[T-Mobile LG G2x] regP:
What ROM and kernel were you running? Even if you are completely stock if it were a re-occurring issue we'd know about it by now. Bootlooping can be caused by many things and is possible on any ROM so I wouldnt count on the update preventing it from ever happening again. This kind of stuff is the reason using Titanium Backup is such a good idea. Schedule it to back up apps and data nightly so that if a crash does happen 99% of your settings, apps, and data can be restored with a few taps of the screen.
[T-Mobile LG G2x] tackleberry:
Keep it. Seriously its a computer in its own way and these things happen. Fix it and mmove on.

[T-Mobile LG G2x] 21productionz:
That's how it started for me a little over two weeks ago. Now it reboots too often, it won't end calls, it calls people like it's possessed, wifi won't stay connected, I'll have 4g in an area one day and no service in the exact same spot the next, overheat and gets hot enough to scare my daughter (one time thing), andmy battery has to be charged every four hours.

Tmobile said (3 reps in customer loyaltymind you) we can't do anything about it because it's a known issue.

I am very upset about this

And to make it worse, one rep asked me why I didn't return it under the remorse period. I told her this started after my remorse period ended. They won't even send me a new g2x. I'm gone from tmo (sadly there is nowhere to go)
[EVO 4G General] Mark_Hardware:
OK, So I'm trying to (re)root my evo, but for some reason "USB Debugging" is not showing up, and the phone doesn't show up for Unrevoked. I have usb debugging enabled, I've tried checking it and unchecking it and restarting the phone several times, several ways.... No changes. Any ideas?
[EVO 4G General] HipKat:
The drivers aren't installed.

Run HTC Sync, which installs your drivers, then uninstall HTC sync (Just the program, not the drivers)
[EVO 4G General] Mark_Hardware:
Problem fixed. Hell if I know how. I plugged it into a different computer, and usb debugging showed up like normal.

Plugged back into normal computer, everything is a ok. IDK, but I'll take it!

Now I discover that unrevoked doesn't seem to work after the latest update. sweet.

Thanks though!!

[Nexus S General] J3ff:
Have a boss and a coworker who just picked up the Nexus S 4g...

Currently I've got an Epic that's got a real nice fast stable ROM on it, so I didn't opt for the upgrade to the nexus, thinking I'd grab a dual core phone when one came out.

To the question: Boss and coworker are tech ppl, do you think it's worth it to upgrade them to different roms? Cyanogen would be what I went with. However, the whole reason this was required on the Epic was because of the awful job sprint and samsung did with it. With this being a pure google phone it seems to be nice and fast right out of the box. I noticed the GPS is a bit weak, I guess that's normal for samsung crap?

Anyway, what do you think? Keep in mind they aren't going to be happy if their phone breaks on a friday/sat/sun/worknight/vacation because I put a ROM on it.

Would you do it? Or just Root them and leave it stock?
[Nexus S General] zephiK:
I'd just leave their phone stock. It's your boss / co-worker, rooting your phone requires maintenance. The current CM7 stable is running Android 2.3.3, the nightlies are on 2.3.4. 2.3.4 is far more faster. Nightlies are stable, but a few bugs need to be tweaked out.

Besides, I wouldn't do it on my bosses' phone. Anything goes "wrong," its your fault.
[Nexus S General] nowens0520:
I would try openSoju its fast and incredibly stable. Not a huge improvement from stock though.
[Nexus S General] J3ff:
so there isnt a huge upgrade from stock? what are the differences?

Like I said I know on the epic, it was speed, gps actually worked, etc.
[Nexus S General] zephiK:
+ Extra Speed (Yeah NS is fast.. but even faster when you mod it)

+ Custom Kernel (This is the huge one)

... Voodoo Color

... Voodoo Sound

... and more (visit a kernel thread for its full features)

+ Notification bar widget (your pull down.. those buttons, they're customizable)

+ Music Control on lock screen

+ Lock screen mods

basically everything. go do your own homework on these ROMs. everything is right there. I don't want to just paraphrase what is already said. Just go to the dev forum and look for yourself.

I personally wouldn't mess with their phones because its their phones. They should decide for themselves.

Rooting and flashing ROMs requires maintenance. If you don't flash a newer version a bug can mess with your phone from causing it to be a day to day thing. What if a new OTA comes? You'd have to update their phone (or themselves if they even know how to).

Basically, if you root their phone. Their phone's responsibility is built upon you. If you want that burden then you can root it and do that, but I personally don't want that. Up to you.
[Nexus S General] mikeyinid:
I would root their phones, just to do it ;D

I would also leave it stock, other than netarchy kernel. Thats the setup that I always go back to, very solid, fast as hell at 1.2ghz, and no maintenance or issues to worry about. The NS4G is very fast out of box, but I still notice a few hang ups opening and closing certain apps with the stock kernel. The netarchy kernel makes that stuff almost non-existent. Plus, if you say they are tech people, they will like the options being rooted adds to it. Just my thoughts...
[Nexus S General] J3ff:
yes I already rooted them for them.

I was just wondering if it's worth a custom rom/kernal.

Maybe I'll throw a kernal on the bosses phone... he'd notice the difference
[Nexus S General] jonnythan:
FYI, there is no CM7 stable for the NS4G. The nightlies use 2.3.4, which is all the NS4G ever had.
[Nexus S General] jonnythan:
Well if you're already rooted, you're already committed to maintenance when it comes to new software releases.

Install a new kernel on there and add BLN Control. That's really all you need to do.
[Nexus S General] dreamsforgotten:
Flash mikyinids deodex rom you'll get the netarchy kernel and the option to theme or add on things like the quick panel yet keep the is stock.
[Nexus S General] Award Tour:
Two options in my mind:

1. Keep it stock but rooted and flash a custom kernel for voodoo +BLN.

2. Flash MIUI.

MIUI is a little buggy, has no WiMax, requires maintenance and constant flashing so I'd stick with #1.
[Nexus S General] eagercrow:
I'd do flash a kernel and install setcpu and adfree. I've tried every ROM out there and always go back to stock. I have yet to try a ROM that works 100%. This google ROM just works.

This phone isn't like others, we don't have bloatware that needs to be removed.
[Nexus S General] tommyz2kool:
On CM7 nightly 17 w/ netarchy kernel and running UV voltages and everything has been super stable for me. I use my phone for work.. lots of voice, email and texting and never had a crash or anything. The only weirdness is with voodoo color when I unlock the phone. Another weird thing is the lag when I use the dialer with a BT headset. other than that everything works great.

I'm not sure where to post this sorry if I added an unneeded thread all. However, I needed to know if the Lg Optimus C from Cricket will work using some of the other Optimus Roms such as Optimus V and such. I know they are the same phones different carriers, I also know the source codes have to match for the roms to work (or something like that).

I am asking this question cause I plan on buying the Lg Optimus C, however, I don't want to buy the phone if I can use custom roms and themes and such with the phone. I know I can boot the phone into clockworkmod recovery, Just not sure if there are any custome roms on this site that I can use with the phone that will work with Cricket service.

I do have slight experience using clockworkmod and flashing roms using my Zio M6000 Cricket phone, but haven't messed with an Lg Optimus C at all yet.

[HTC Sensation] Desreil:
From what ive been reading, seems like the EVO 3D is a bit smoother since is has more accessible memory compared to the Sensation 4G. When we finally get root, will uninstalling all the bloatware crap free up space and thus give us a smoother experience? Or is it just the way Sense has been written for this device that makes it this way?

I understand the lag is extremely minor compared to the EVO 3D, but i wonder if removing the tmo bloatware (which i want to remove regardless) would aid the lag.
[HTC Sensation] Paging Dr B:
It's hard to say, but I can't imagine that they can't resolve some of the lag with a simple software update.
[HTC Sensation] borodin1:
Yes, it will be a lot smoother. Same thing happened with MT4G: T-mo preloaded bunch or useless crap on it and MySense was crawling to a stop after few days. As soon as S-off was achieved and custom roms based of official rom started coming in, people immediately noticed increase in battery life, more stability and, most importantly, buttery smoothness of the phone.
[HTC Sensation] xnifex:
Also, all the crap Tmobile put on the phone is running all the time! If you kill the processes they just restart right away.
[HTC Sensation] Desreil:
sounds great. will be looking forward to rooting and removing these pesky tmo apps. I wonder if Sense itself plays a larger role in the whole memory hogging. i dont mind but that just give me more reason to rid of some of those useless apps.
