Hi guys. I'm new to the Android modding scene and I just installed my first ROM yesterday. Now my Droid Incredible is currently running MIUI 1.9.9 with the latest Incredikernel, undervolted by about 100 units.
When the phone is in sleep, the battery is no problem. Over the course of 1.5 hours I lost 2% of battery. However, I sat down and opened up browser (on 3G Data) to read a couple of articles, and in the course of 3-4 minutes, my battery went from 77% to 72%.
I don't know if this is normal, this is the first time using a text-based battery readout instead of a graphical, so maybe I never noticed it before...but I can't help but find this to be unusual. Are there any ways to fix this? Should I undervolt more? Switch to a different kernal? Flash my radio (I'm at Stock Froyo)?
I've looked around and can't find much on the issue (1.9.9 is new, I figure that is part of it), but perhaps you guys have some ideas for fixes?
EDIT: Upon closer look, it's only happening when using 3G Data, using wifi for the same thing and my battery has stayed at 71 for 10 minutes of browsing now. Also Camera drained 3% really quickly...but that was trying to use burst mode for 20 seconds, so I'm sure that was why, but just adding it as a note.
Battery Drains like HELL!!!

You are doing much better. I recently flashed 1.9.9 and initially it was choppy and lagged a lot. Then someone recommended Fugumod kernel. Although, it appeared as if the lags were removed, the display became dull and yellowish. I installed Voodoo color app to fix this issue to some extent but it was of no use..
This is just the beginning... I caliberated the battery yesterday and used it until 89% before I went to sleep.. Today morning, the battery had come down to 59% for no apparent reason. I searched the 'Battery monitor' for some information about this and found none of the services/apps were used for more than 15 minutes and yet the battery had drained the hell out.. The 'display' was at 60% and its duration was the max(~4 hours) and around 4mA of current..
To make matters worse, I rebooted the phone and the charge fell from 59% to 8%... just for a REBOOT!!! and Fugumod kernel doesn't allow me to charge with the phone switched off... This is annoying too.
I am severely disappointed I've never encountered such a disaster before.. There is absolutely no evidence as to what caused this battery drain.
Is there a solution for this? .. I'm charging my phone so that I can flash back to 1.9.2 and the stock kernel..
Any sort of help would be appreciated.. Thanks
I'm hoping to get some help on this. I have a T-mo Galaxy s3 and I'm currently running the latest AOKP Milestone 1 rom, which by the way is incredible. I do not use my phone much at all, I send texts, surf the net every once in awhile and that's about it. The battery seems to be draining very fast which I would understand if I was using it a lot. I took it off the charger this morning around 5:30 a.m. 100% charged, and its now at 87% at 7:30. I really haven't used it for anything, so it's basically been on standby. Is that normal battery drainage? I'm just wondering if there is some setting, turning something off, etc that I'm missing to help with this. Thanks in advance for any suggestions.
The battery life on JB roms has been less than ICS. Its known and dev's are working on it.
You would need to check a few things and your not going to get a yes or no answer. Post your screen on time as well as whats causing your battery drain.
Is it going into Deep Sleep? check with CPUspy
What are your data/wifi settings? Leaving these on when not needed or in bad reception areas causes increased drain as the phone looks for service.
Hi all,
I've been reading quite a lot about this spurios wlan_rx_wake keeping ANdroid OS eating battery and not allowing deep sleep on some WiFi. I seem to have same problem, however I cannot change the setting of the wifi router, so I can only go back to disable wifi in sleep (not an option, as this seems to have bad impact on my battery and data plan) or some other solution. Does anybody have an idea how to solve this?

I have this too. I've done a lot of searching around and can't find a fix.
My rooted/ROM'd GNex is affected as well as my completely stock N7.
My N7 is much worse actually, maximum battery life is roughly 24 hrs w/ 1 hr screen on time. That is AWFUL, seeing as it used to last 4-7 days w/ 2-5 hrs screen on time, depending as usage.
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?
Hi,
I bought the phone in November 2022. Since the day one I experienced issues with battery life but I thought that the phone needs some time to update itself etc. It was loosing around 3-4% in deep sleep which makes around 20%-30% during an usual night. I mean that's a lot compared to my previous phones.
After a month I started changing different settings to check what is happening. No app or setting seems to be draining the battery at least it's not shown in phone setting and AccuBattery which I'm using.
I found out that changing services from LTE to 3G improves the performance dramatically. 5% during a night. I know that LTE drains battery faster than 3G but come on it's between 6 to 10 times better with 3G that LTE.
I already filled a complaint with the shop I bought the phone in but they didn't find no issues with it. I think it must be some kind of a service or process that it's draining it but I don't how to find it and fix it.
Please help, it's driving me nuts!
You need to debloat and change a bunch of settings to get a decent sot and idle drain. With normal use sot in 24h total ("normal use" is of course different for each). Not sure if attaching links here is allowed but here is debloat list and the battery tips. Have at it.
