Hi, I just got a TMO Wing. Thanks for many threads here, I downloaded Statusbattery and overclocked my wing to 247. It works great. I have a question regard the accuracy of batterystatus. I underclocked to 156Mhz just to save battery yesterday so it can last a bit longer until I can recharge it at home. However, I found that the current drain shown in batter status is 177mA. I changed it back to 201 MHz, it show 112 mA, but if I overclocked it to 247mA, it showed 64mA. What just happened? Is something wrong with my phone? I thought that the lower the clock goes, the less current it drains. And all the cases were when Wifi and bluetooth disable. Only the phone option is on. No other background app is running.
Best regards
it's called batterystatus, first of all
anyway. Its possible that the amperage meter refreshes at a different rate than the clock speed. Or it could just be that it's wrong.
Its also possible that the processor is being actively used, even if nothing else is running.
It also could be that a slower clocked processor needs more power to get things done than a faster one because it takes a longer. The faster clockspeed finishes quickly, so it can idle at 64mA.
Your guess is as good as mine. Try setting it low, then waiting a while
Updated section:
After clearing cache through recovery and doing a hard reset, the uAh has gone back to 3142000. Standby time seems good with the battery losing 7% overnight. It does charge quite quickly from 0-100 in about 2h. The previous heating issue remains with cpu monitors showing that the cpu jumps to high clock when I touch the screen. I don't see any change in which apps use the most battery with the screen taking up the most as before the problem started.
The heat appears to be what is draining the battery but I can't find any single app that causes it to ramp to max.
Pictures:
No-frills is set to stock settings to see how the phone handles the actions
2nd picture is when phone is idle
3rd picture is immediately after swiping through a few tabs and scrolling through some pages in the app which causes cpu clock and load to increase
Old sectionFor when battery uAh was low)
I've had this Z1 for about 11 months. I can only get around 2.5h on screen time with regular usage. The battery uAh was only 1848000 Recently it fell to the 1700s. Calibration appears to reduce the value further. The phone seems to heat up in about a minute or two no matter what app is running.
The phone is rooted on stock 4.4.2
I have tried updating to Lollipop before but received an error due to rooting, so I don't think anything changed.

sounds like it's time for you to replace your battery.
You may try to disable the "input boost frequency"
By default when you toch the screen, cpu frequency of two cores instantly jumps to around 1400 to preventing any lag but it seems to use more power and causing heat
I have disables this and since then I'm no longer have any heat issue and also the battery life is so much better now but you may exprience a little lag while scrolling on heavy web pages but thats all
Btw i'm on .157 and using Kernel Adiutor for cpu tweaks
You may disable this by the app mentioned above or by editing sys.somc.touch_perf_kick=1 from 1 to 0 in buid.prop or adding this line
Anything is valid. Preferentially without root.

What is your current battery performance? Is your device affected with the fingerprint sensor bug that locks the CPU at highest frequency?

About 6-8 hours in moderate-high use, I guess. I don't think it is, how can i know?

Install a hardware monitor app like CPU-z or DevCheck. If you CPU frequency is not coming down from the highest value (for 4 small cores: 1843 MHz and for 4 big cores: 2208 MHz), you are most probably affected by the bug. You can disable fingerprint sensor to conserve battery in that case.

If you are talking about SOT, it's quite normal.
You can't really improve SOT.
It depends mainly on two things : Brightness and Kernel settings. Kernel you cant tamper with without rooting/unlockin your phone, so the best improvement can be achieved via auto brighness.
If you are losing too much battery while phone is idle/screen locked, here are some steps you can follow:
Limit background use of an application from Settings/Battery (Even google play services, notifications still come through)
Disable background data use of apps from Data Usage (Especially facebook/messenger ones, notifications still come through via GCM - use to your own likings though)
Clear Google Play Services cache, as it somehows causes battery drain
Disable location and google location tracking
Disable "Data always on" at developer settings. No point of keeping an active connection while on WiFi
Change network to 3G Only, if your 4G coverage sucks, so it drains all your battery

When i quit the app and come back, the frequencys are at the maximum value for a milisecond then goes to 1401MHz(CPU 0-3) and 1113MHz(CPU 4-7). So, I don't think I have that bug. What do you say?

Auto brightness? Really? I thought that was a battery killer. My brightness is in about 25% most of the time, so, I don't think that is the bigger problem, do you?
Well, thanks both of you guys for the help, and I will follow your instructions(but not the auto brightness one, I don't really like it), Reptant. I will try to remember and report the results at the end of the day.

Yes, that's right. Disable auto brightness, and keep the brightness at around 10%. It is more than sufficient in indoor conditions. Further, disable high accuracy location settings and set it to battery saving or off. You should also turn off WiFi and Bluetooth scanning in location settings.
I personally use a rather far reaching way of force stopping every social media and other news apps after using them (I have never observed any 'misbehavior' as they warn, but it saves a great deal of battery life.). As you can see in the screenshot the battery has lost 7% of charge in 2 hours and it still expects to last for 1 full day.

Min freq should be 633 MHz for the little cluster,it a bug with the 2nd October update, many users are affected,and so i!

Hello, any better result if phone is rooted ? Or any other solution? Thanks a lot.

The suggestions from Reptant above are still valid.
Other than that:
1. Greenify. Set non system apps to shallow hibernation. Try Amplify if you dare.
2. Disable ads. The image/video ads may not occupy a lot of your screen, but they use much more data than text. disabling those ads will reduce the amount of data that the modem needs to download, hence reduce battery consumption. this will have big impact if you surf the web a lot using phone.
3. Change CPU governor to powersave and/or disable some CPUs, reduce GPU max clock speed (you may not like this since it will make the phone laggy)
Hi. Probably not only me having that issue. When battery goes to 20% or lower smarthphone reduces it's GPU power and battery usage. Games became inplayable. I tried to find right settings and fix it but without a result.
I tried to switch off that Battery Optimilization (google-> "How to turn off battery optimization on Huawei devices" (I'm a new user and cannot post links) but with no improvement.
Is there any way to fix it? Must be some fabric setting.
Hi.
Just saw this in Developer option and it was OFF.
I have put it ON for the time being as it says It improves performance and reduces consumption.
Just wanted to know what it actually does and is it helpful to Turn it On or just leave it Off.
Thanks.
Hmmm interesting, I just had a quick read about it and it seems to be universally accepted that it does good things for battery life. I just switched it on.
Don't have it on my device (G9980 on A12), if I had to guess I suppose it should be something like Receive Side Scaling queues in network adapters, that should always decrease overhead on any single core, as long as the rest aren't overloaded.
