[Q] Battery broken?

Hi all,
First of all, this site is amazing. I get a lot of ideas and nice apps from it. I've got a Desire with CM7.0 and ClockworkMod 5.0.2.0.
Recently I've got problems with (I think) an overheating battery. I can't do any cpu-heavy applications anymore (watching Youtube movies for example) because my phone will start rebooting and get into a infinite reboot loop where it only shows the Joker from my AlphaRev S-off mod. The only way to stop this is to take the battery out and let it cool down. The last couple of days it became even worse where I can't even charge the phone while it's powered on.
I already used CPU Master Free to underclock my cpu to maximum of 576 Mhz but this doesn't seem to help.
Anyone know what might cause this?

Check battery health:
Open dialer, type #*#*4636#*#* -> Battery information

Battery status: Discharging
Power plug: Unplugged
Battery level: 95
Battery scale: 100
Battery health: good
Battery voltage: 4109 mV
Battery temperature: 24.1 C
Battery technology: Li-ion
Time since boot: 8:43:31
Seems alright to me?

Upgrade to CM7.1. Just saw you use the old 7.0 version.

I've updated to CM7.1 but that didn't improve it, it's actually worse now. After installing the ROM (using Rom Manager, choosing zip from SDCard) and entering my pin code on the initial boot it started straight away.
After letting it cool down it would eventually boot into Android to start rebooting again after setting up the Google Account and firing up the market. Strangly the phone, or battery, doesn't feel warm at all.
Do I need a new phone already?

At first I would replace only battery. Don't see why you should buy a new phone.

Hi,
Sorry, it took some time. I'm travelling around New Zealand so I have only limited Internet access. I've bought a replacement battery but it didn't solve the problem so it doesn't look like the battery
When it starts rebooting and I remove the backcover to remove the battery, the battery is not warm at all. It's more the part below the battery (behind the trackball)

It doesn't make a huge difference what CPU editors you use, the screen is always going to be the biggest drain on the battery. Also, a 3% drop when you were sleeping from 10-6 is good enough.
Games like Dead Trigger will destroy your battery because not only are you using the screen, you are taxing the CPU/GPU as well. All in all your screen on time could be a little bit better, but considering you played at least half an hour of Dead Trigger and listened to music it isn't the worst thing in the world.

[Q] 10h battery life

Hi everyone!
I want to use my phone as a sort of security camera for around 10h. I'm on latest Slim ROM, with AK Purity kernel, Conservative Governor, maximum cpu frequency set to 920 MHz (of course with lowest brightness and on airplane mode).
With the original battery full charged and an external usb 5600 mAh battery plugged (which can charge the phone 2 times and something more) I can reach around 6/7 hours of autonomy.
Do you have any ideas for adding at least 3 hours of battery life? :laugh::laugh:

I'm just trying to get 6/7 hours

Is your screen on the whole time?

if you are able to do it with the screen off may be you can squeeze a couple of hours , but dont actually know if the camera would work with the screen off?

Maybe with a an app installed that keeps proximity senzor on all the time. This way you can put a peace of adhesive plastic or something over the senzor after you turn on the camera. Voila! Camera working and screen is off. Only problem is: it's a very expensive device to use for a camera. Not worth it.

Can you explain this better? What is the connection between the proximity sensor and the camera?
I'm using a motion-triggered app to record, because the internal memory (~13 gb) of course cannot store 10h of recording in 1080p, and it needs the phone to stay awake in order to work. Do you know any other apps which work with screen off?
Thanks for the help by the way

Used a Voltaic V60 (would give you a link but XDA says I can't since I'm a "new" user) for my thesis project in college. About the size of 10 standard extended batteries. Will probably be a little overkill, but definitely an option.

Horrible battery life on newish S4 Mini ("best" performance <3h)

Hey guys,
after dropping my beloved Nexus 4 to the concrete floor in May, I bought a new S4 mini in the electronic market because of it's decent size and all the fuzz about having a very good price-performance-ratio.
After a few weeks I already was fairly disappointed.
On an average work day (without WiFi) and little use (~30min OSD) the battery wouldn't last a full day. I tried the usual things like turning off GPS, bluetooth and using Wifi whenever possible (turning it off, when not in range), etc. I also used the App greenify which boosted my deepsleep in Wakelock Detector to stable 85+%.
When using GMaps/navigation my phone is getting hot (~50°C) and battery is drained within minutes. When trying to navigate out of the city (<15min navigation) one day my phone was discharged within 3 hours after a full charge. I got Wakelock Detector, Better Battery Stats and Battery Monitor Widget installed.
The only thing I found out, that when I am connected to Wifi the drain is a lot lower 1-2%/hour compared to when I am using 3G/H+ which results in 7-15%/hour (both when not using the phone), although there is no problem with signal quality. Recently my phone started to bottoming out rly hard when hitting the 20% mark. From there I can watch the battery dropping to 0% within a few minutes.
Things I tried so far:
- turning off features that are not in use (GPS, bluetooth, Wifi when not in range)
- make sure phone gets into deep sleep/greenify apps
- recalibrate akku
- reduce brightness & disable auto-brightness
Setup:
GT-I9195 bought in May 2015 from electronic market chain
CM 12.1 (Android 5.1.1, serranoltexx)
Standard CM Kernel
Baseband I9195XXUBML4
I can provide Screenshots from BMW, WD and BBS. Any ideas how to solve this or what else I could do?

Probably you should use something like better battery stats, to check
- if a service is going mad, then turn it off with disable service to test (most times happens with unclean flash)
- if you have an app with wakelocks
If you can't find anything that way, might be a hardware fault.

Personally if I came across this problem I would return the phone to stock Android and do some tests, see if the same happens again. CM12.1 can have issues across different same model phones. Try the Samsung Phone Info app to see how old your phone is. I'm guessing it was second hand? Some older revisions of the Mini had battery problems. Maybe a new battery is needed? Maybe.. As for the battery draining 20%-0% in minutes I have also suffered this on a brand new March 2015 device. Not all the time though it only happens with randomly once a week. But I put that down to the battery not been fully calibrated and then drained and recharged over the next 3 4 days, as I use a spare battery and swap out the batteries regularly which means my battery is very rarely calibrated.
All that said though I can easily get through an entire day if not 2. And using stock I'm able to get 4 and a half hours on average every time, maybe 4 hours of screen on time when using 3G a lot and GPS etc.

I have had the same problem as you.
I return twice my phone to vendor. But they could do anything.
I solved it with undervolting and underclocking my phone (only the low frequency).
I read from someone, you can undervolting 150 millivolt.
My experience, is undervolting 125 milivolt. and underclocking the low frequency at the minimum.
You didn't feel any difference, behalves that the phone is cooler and battery live is better.
My WiFi and Bluetooth are always on. I don't have to recharge my phone during the day.
It is so effective en transparent that I don't understand why Samsung didn't do it natively.

Hey,
I tried to apply some of your advice and flashed the newest stock rom for S4 Mini (Kitkat ...COE4).
In that process I recognized that the Baseband is not updated by CM and that the one that was installed when I bought it was fairly old (from 2013). Do you think that this might be part of the problem? (I sort of hate the Samsung Rom)
This week when working and not having Wifi all day, I managed to get 2h of SOT and still had around 25% left which I couldnt have gotten before imo. I only lose 1-4% per hour when the phone is not used. But still thats not pretty good, when ur saying you can get 4h with GPS and everything. I also didnt use GPS. And today when I restarted my phone it just went from 40-ish % to 15% without any reason. Any more ideas?
I installed BetterBatteryStats today and will try to give some more insight the next days. Wakelock detector said that I had 85% deep sleep (timeframe 1 day 2 hours).

No I bought it new from a electronic store (Media Markt). The app says that is was made on Oct 19th 2014 in Vietnam and that it is original/not refurbished.
How much do you gain by undervolting (SOT or % per hour when idle)?
How do you do it?

maybe the best way is to downgrade by flashing CM11 for example ...
(another way with stock + Alexax kernel + own debloat&freeze ... )
I have the same consumption problem with Resurection Remix LP too ..... very strange !
Lollipop is supposed to be less angry than Android 4.X.X ... but it seem have problem somewhere for our S4-mini sources maybe ,i don't know ...

This night I did some BBS tests:
Setup:
Stock Rom I previously installed (see posts above)
charged phone during evening
set up custom timepoint before I went to sleep
WLAN disabled
all apps greenyfied except those I deemed significant that they keep running (Whatsapp, calendar, Swiftkey, BBS, BMW, etc). Forgot newly installed app hoomn.
I had to upload the logfile to pastebin because it was too long for the xda forum: pastebin.ca/3256568 (I am not allowed to post URLs, sorry)
I lost 14% of battery during 9hrs (-1,6%/h). That's probably not too bad?
93% deep sleep, 33min awake time
Weird things I discovered/things I did not understand:
- negative Voltage loss?
- Wifi runtime 100% although I disabled it
- dominant wakelocks (count > 100, all of them < 30s): Alarm Manager, RILJ1, *net_scheduler*, GCM_CONN, ContextManagerWakeLock, Event Log Service, AlarmManager (com.sec.spp.push.Samsung Push Service), SyncLoopWakeLock, GCM_HB_ALARM
- dominant KWLs (count > 100): ril-fd (25min), bam_dmux_wakelock (13min), radio-interface (7min), PowerManagerService.WakeLocks (3min), mmc1_detect (1min), alarm_rtc, alarm, sec-charger-monitor, smdcntl0, pm8921_soc_lock, power-supply, KeyEvents, smsm_snapshot, qmuxd_port_wl_0, qmuxd_port_wl_1, smdcntl1, mmc0_detect
- Alarms (>20): ccc71.bmw (Battery Monitor Widget), android, com.google.android.gms, com.sec.spp.push
any ideas/assessments?

Zenfone 5Z stock Rom and thermal throttling charger - How can I change this behavior?

I'm almost sure this is a kernel setting, but I decided to ask here first because I've already soft bricked my 5Z when trying to root it. It's merely got an unlocked bootloader with the most recent stock ROM now.
I use this phone as a backup processor (its snapdragon processor is 50% as good in processing as a Ryzen 3700u to my use, which is amazing considering it's a phone). As with every ARM, thermal throttling soon kicks in and the performance drops. I solved this partially by having two 120mm fans, one blowing in and another taking the air out of its case.
Depending on the ambient temp, it carries on processing with 5-6cores out of 8. It's impossible to use 7 or 8, because the phone automatically drops the current being drawn from charger - even though the battery itself isn't hot (with the cooling, it never gets above 37 ºC which is safe for a phone). So what happens is that the phone eventually dry the battery until it dies and turns it off.
How can I change this behavior? It seems that root wouldn't solve this, as far as I know root would only let me control cores and frequencies, but the kernel would still stop the charger in an attempt to cool off. I would like to keep the charger drawing as fast as it can (2.7mAH from my tests) and let the CPU/ARM self regulate its performance to deal with heat, and finalLy be able to use the 8 cores.
Is this possible with a custom kernel? Or is it some configuration buried deep in the usb port that cannot be changed?

Follow up: the problem is not with the charger, or the port. 10 seconds after I stop the processing and the heat is dissipated, the phone goes back to charging at full speed.
