I am running CM7 on a D2 and i am experiencing pretty short battery life. I went from Liberty 2.0 rom on froyo last week, and upgraded to GB and flashed CM7.
I have barely used it much today for example. Took it off the charger at 6:30am have done nothing more than sent a few texts and browsed a website for about 10 mins. It is 10:30 and i am already at 70%
I did a proper battery stat reset this past weekend also.
(i have also been getting a lot of random force closes)
since i cannot post pics here's relevant info...
Android version - 2.3.5
Kernel Version - 2.6.32.9-gca08d89
Mem Info - 214/475
Mod version - CyanogenMod-7.1.0-RC0-DROID2-KANG
Build Number - GRH78C
Battery info...
Display - 42%
Phone Idle - 18%
Cell Standby - 15%
everything else is under 8%, Android OS and System at 2%
CM7 GB Battery Issues
I am having this problem as well. Ever since I rooted and installed Rev's CM7 GB build a few days ago battery life has been much worse. I tried installing Jake's Mods V13 but if it is helping it is not helping alot. Yesterday, made 2 short phone calls, sent 3-4 texts, browsed web for maybe 10 minutes total, and was on tweetdeck for maybe 15 minutes. By end of the day was down to 30% battery. Pre-root and CMY probably would have been about 60% - 70%. Here are the battery stats when plugged it in at bed time last night:
15h 16m 23s on battery
Cell Standby 55%
Phone Idle 19%
Display 13%
Voice Calls 9%
Android OS 2%
TweetDeck 2%
Has anyone figured out a solution to this? Really liking CM7 but I am afraid to play a game or something on the phone because I'm afraid I will run out of juice!
CM7 does have a shorter battery life than stock and some other ROMs. It's still the best ROM and it will eventually be back to better battery life. I use SetCPU and JuiceDefender.
Should I go into the CPU settings on my phone to find ways to increase my battery life? If so, which setting should I alter?
I have been using the 1Ghz/undervolt option in Jakebitesmod along with Juice Defender and it seems to be helping. Battery will usually last me all day with moderate use.
You might want to try SBFing back and starting from scratch. I was on Liquid 3.0 and has atrocious battery life due to the 'Idle' process and was seeing 10-15% battery life drop each hour when there was absolutely no use.
I switched to CM7 and things were much happier. Maybe 10% loss after 4 hours idle. FB app did drain the battery once but I think I backed out of it while it was loading so it was trying to load GPS or something but outside of that no battery life problems what so ever.
I have very bad battery life since 4.2.2. Trying to understand why that happens. I had around 3.5-4 hours SOT in 13-14 hours total usage which is very fine for me. I don't have very good reception, I know this drains battery but I'm living in same place so reception is still the same. Tried most of the roms and kernels. Flashed everything to stock 4.2.2 manually too but now the most battery life I can see is 2-2.5 hours SOT in 7-8 hours total. This is terrible compared to people at forums. Especially my screen started to eat battery too much, consumes %10 of battery in 25 mins. Even if I don't run nothing, don't use cpu, just kept cpu at 384mhz and screen on to test. I don't know much about these things but started to think 4.2.2 radio may have problem with me. Is that possible? Or what should I do? I will be really appreciate with your comments.
No. It's fine. Update the baseband if you choose to.
Also, how's performance for you?
I'm running a build of Exodus 5.1 with the boeffla kernel, and I'm getting around 3 hours SOT from 100% to 0% battery. That said, I have it set up in a way where I have zero lag (not using performance governor) and I'm getting 76206 on Antutu. with. I've also got Greenify and Amplify.
Just as a side note, how is your charging? I'm getting around 200mAh in (from my best cable and charger) boosted to around 650mAh using boeffla settings. Isn't that a bit low?
Atleast for me and my OPO, only the original charger and cable gets reconized as AC Charger, everything else i plug in as USB Charge, thats why the chip is force values around 200-650mA.
Boeffla Kernel can show u that, if the app says "Ac Charger" + a mAh value then u'r good, if it's not and just shows only a mAh value instead, the Cabel and Chager are reconzied as USB Charger therefore the IC Power Chip limits the throughput.
Sultanxda's 5.1.1 caf rom. Can easily bit 6-7 hours sot. Stock kernal
Before switching roms you should try wakelock detector and/or better battery stats to see if something is keeping your phone awake and killing your battery.
I don't worry too much about benchmark scores, focus on how your rom runs for everyday usage. Performance is just fine for me, but I don't play any heavy games on my phone though

Stock ROM and Boeffla Kernel, 6 hours of SOT with a battery friendly configuration (light undervolt, small underclock and balanced governor), but performances are still great with no lags. However with the stock kernel I never went below 5 hours, which is already a great result
used to have 8h SoT on KitKat. any lollipop / MM rom gives me max. 4h.
Darkobas best battery for me. Around 6 hrs. Then Herna's Omni and RaCyan: more than 5hrs.

slimsaber 0r Omni 6.0.x and sultan CM 13 06/12. CM 07/12build all giving 5+ hrs SOT for me.
I got about 5.5hrs on data (mostly LTE) yesterday across about 14-15hrs usage.
Sultanxda CM13 rom. Everything stock. No greenify and amplify and stuff. Turn of keep awake and wake up for google play services.
recently switched back to kitkat after realizind nobody was gonna fix the sitty battery life on 5.x and upwards. Not regretting my decesion. Bear in mind this is a one and a half year old phone that has seen daily usage, almost half of it was on 5.x, waiting for a battery drain fix. When it didn't come, I came back to 4.4.4 and I'm happy to say my battery is still healthy (was a bit worried all those months running a battery draining rom would have strained my battery). Cant tell you anything about charging since im using stock kernel on official CM11S with a stock charger, other than the fact that it charges really fast. Performance is so good that i decided to try and undervold (to 1950~) and im seeing no noticeable difference. Device is nice and snappy. I'd wholeheartedly suggest a switch to kitkat for the time being for anyone that wants to max out battery usage.
Note: These screenshots were taken after only the 2nd battery charge cycle so the battery still isnt calibrated all the way. After a few more charge cycles, i could probably get back to what i was used to on kitkat in terms of battery life: namely 8h screen time.

My phone running on stock COS12.1 and can get around 7-8 hours of SOT with WiFi in 1 day usage. On 2 days usage SOT 5 to 6 hours. But on Mobile Data I getting a 4 to 5 hours of SOT. For charging I using Apple's wall brick from old Ipad and original OPO cable - 0 - 100% in less then 2 hours.
Sultan cm13 nov build. Getting constantly over 5hr sot with LTE. Standby time 12-16hrs.
Disable the wakeup for google play services.
I'm on sultan's 01/01 cm13 build. Currently have 1:43 sot and am at 78%. Was at 92% after upgrading. So that's 7.357 minutes per 1% battery, or 12.26 hours SOT. Wakelocks are not an issue here because this is continuous use on about 30% brightness, wifi and lte on, sync on, Web browsing and YouTube only (no gaming). Completely stock build with no power saving bs. Sultan for president!
TLDR; depending on your useage, 12 hours SOT on cm13 is possible.
4.4 with cm11s
I've never had more than 2 hours SOT with any rom (stock, sultan's caf, exodus, and others), do I have a battery problem?
5,5-6h SoT with Fusionjack's SlimSaber 6.01 which is based on OmniROM Sources. I'm using this ROM without any modifications, like custom kernel or xposed, neither i'm using things like greenify or similar. I've just tuned the power profiles to save battery while screen is off and limited max cpu frequency to 1958MHz to prevent heating. I'm using Facebook+Messenger and WhatsApp, which are by far the biggest battery hoggers and running Google Now with on Tap with GPS at hight accuracy the whole day. So the reached SoT is absolutely nice. Calculatory that would mean, without Facebook, WhatsApp and deactivated GoogleNow and GPS i could easily reach 8h SoT, but i prefer the comfort over the battery life, coz that's why i'm having such a smartphone.
Sultanxda CM12.1 rom w/ the kernel it comes with. With LTE/WiFi mixed use all day, getting 5-ish SOT and 24 hours battery life total. Installed Greenify but have it limited to hibernating 3 apps only. Likely going to fool around with profiles to see if I can squeeze an extra 3-4 hours out of it.

Hi, I'm running the same setup as you, I was just wondering about the level of screen brightness you are using? Is your phone running on full brigthness, 10%, 50%, 70%? And are you using apps like greenify, nap or anything similar?
I'm getting good battery life with your setup but not as good as you. My screen brightness is always set to full and I'm sure that could drain my battery faster. So I'm just curious to about what level of screen brightness everyone is using approximately to get these kind of great screen on times. I'm just super impressed and hats of to you and everyone who achieves this lenght of usage!!

I got best battery with Darkobas, but my best is around 6. It depends on alot of things: your battery, your signal, your usages... I think my battery is old and the signal here is weak. So you can only compare to your battery life with other roms, other kernels...

I definitely understand that and the factors there is. But I was just wondering if those who are receiving 6+ SOT have their screen brightness turned down or if their screen brightness is fully turned up.
I've had my Note 4 for just over a year, and over the past few months I seem to be getting really bad battery life. Today, for example, I'm at 47% with only an hour of SOT (light stuff, no gaming or GPS).
Not only is my standby time terrible (2-4% per hour), but SOT is insanely bad - when my battery reaches 30-40%, it tanks in less than an hour - the other day, I went from 56% to 12% in 25 minutes!!!!
I'm running stock firmware and kernel, greenify, frozen bloatware, etc. I recently installed Xposed + Amplify to see if that might help, but it doesn't. I'm looking at wakelocks and there isn't anything that looks suspicious. I did, at one point, install a custom kernel and underclocked it, but that made an insignificant difference.
I have two batteries, and the performance is the same, so I know it's not that. I also use my device at the lowest brightness I can - location services are disabled unless I'm driving.
I do a full wipe every time I install a new ROM.
Does anyone know what else it can be? I need the SOT to get back up to 4-6 hours.
Hello all,
I've had my 6P since launch, and I've tried everything lately but my SOT has been poor (1h-1h30).
I've tried MM unrooted, Nougat unrooted, MM with Greenify, MM with Greenify and Amplify.
Basically the phone is rarely awake with screen off, but when the screen is on the battery just drains very quickly. I'm sure there's nothing keeping it awake, it just seems that the battery is "wasted" when I'm using it.
I installed ElementalX kernel to test, but that didn't seem to make a difference.
Any thoughts?
Thanks a lot!

That is really low for sure. Is your screen brightness cranked up? Playing a lot of games or cpu intensive apps?
Install betterbatterystats or gsam battery monitor to see what is draining the battery. If using gsam, ignore high usage of mediaserver unless it also shows high usage in your stock battery stats as well.
I believe ElementalX kernel is basically the stock kernel, but allows you to make more changes than stock with it's companion app, Ex Kernel Manager. I'd try Ninja kernel or Franco kernel instead.
If no apps show abnormally high usage with battery monitors it could be time for a battery replacement. They are only about $25 if you're comfortable opening it up.
That's odd I had same issue my thoughts are possible virus something that would turn off encryption.
Everytime I turned off my phone when it powered on it wouldn't ask for password after clean install it would for a few days but now with naugut and on a new wifi that haven't seen me before was able to get factory reset and be fine and my battery has gone from lasting barley 12 hrs with screen mostly off to having around 55 left at 10 hrs
right now I'm at 69% for 9 hrs have 22 hrs left.
Also check your top apps for use Microsoft office for Android was really killing my battery also.
