[Q] Odd battery spikes adding to battery hell

I've been having general horrible battery problems with my Sensation on stock Sense and Miui.us. I just installed HyperSensation and Faux 0.2.3 kernel with a full wipe and reset the battery calibration thinger.
First 2 charge/drain cycles were yesterday (got around 5.5 hours as has been normal for the last 2 weeks) and after the second drain to 1% I plugged in AC and went to bed. This morning I checked Battery Monitor (not the Beta or paid, so I'm aware the mA reading may be incorrect/offset on Sensation).
The graph overnight shows some odd spikes every 50 minutes draining the battery. This is the first night I've been looking at my graphs so I'm not sure if this is regular or a separate issue from my normal battery hell.
I've included a screenshot of everything I could think of including Battery Monitor and SetCPU profiles. Re running apps, some I've never run before, the only other one on the 2nd page was Thumb Keyboard.
I would really appreciate some ideas on my battery life in general, and what this issue is in particular.
Background:
- Horrible battery problems with my Sensation on stock Sense, Miui.us and now with HyperSensation ROM-CM7.1 with kernel faux123v0.2.3r.
- Been getting around 5-6 hours with normal use, no 3G, no wifi, no GPS, no Bluetooth, low screen brightness, etc etc.
- I also uninstalled Gallery as I was getting the sensor usage issue which I thought may be causing my battery woes, but no dice yet.
- I prefer to keep data on at all times (2G) as that's what I use my phone for, so I don't use this Juice Defender function.
Thanks,

How did you calibrate your battery? Did you..
Flash Rom
Kill battery to 0%
Charge fully 100% then wipe battery stats? Or did you wipe battery stats as you flashed? Thy could be a major problem
Also you have CPU your max set to 1.56ghz when its charged. That could cause the peak in usage. Especially if you have it set to performance and not ondemand. Those are the only two things that's really stand out to me.
Also check the arhd thread. In one of the last pages (depending on when you get this) there is a link for a fix on battery drain on fauxs latest kernel. Check it out

Thanks rddocke, I will check out the kernel fix. I did wipe, flash rom and reset the battery stats at the same time. I will definitely try your method, I didn't realise I had it upside-down.
As for the spikes, they seem to be continuing today, I can post screenshots later. Given that the major battery user is "Adnroid System", would this narrow my issue down to the built in apps?
On the plus side, with the new setup today on my 3rd battery cycle, I am getting better battery life than before aside from the spikes.

ya the spikes could be do to an auto update, maybe background sync... any things could cause it as long as it isnt a constant high usage i wouldnt worry about it. but if you want to help your situation i would set back my cpu max to 19200 when charging, and clock back to 1.2 for daily use, switch your goveners to ondemand and get them off performance.
basically whatever its doing at those times its running at the highest point your cpu can handle. adjusting wont solve your problem but it will reduce the amount of battery it uses
idk its hard to tell android system is always going to be the juicer, that and sense. nonsense for arhd could help you out too. i particularly like sense tho
hope i helped

I'll change these settings as well, great. I feel like I'm getting somewhere gradually, been spinning my wheels for a week on this.
I can't 'thank' you for some reason, but my buddy should have just done it, which is fair since I can finally pester him less about my battery problems and pester other XDA members instead!

No problem buddy glad I could give you some help. Let me know what you discover from all that. Another tip I could give is maybe test out a bricked kernel 1.4rs or 0.91 seem to be working best with sense 3.0 from what I've read

[Q] Samsung Galaxy S2 GT I9100 heating up

Ello Folks,
I'm new to this forum and for some stupid reason I can't post within the forum I wanted to, so I hope someone can help me here..
I have been playing with Custom Roms for a long time and I have ALWAYS encountered problems regarding battery drain. I have searched innumerous times for ways to fix it.. I've tried many different ROMS and KERNELS and I always ended up with a massive battery consumption with little use. I then thought it was my battery as the device is quite old so I decided to buy a new original battery and still having the same problem.
I am starting to think that I am really dumb and doing something wrong or maybe I am just unlucky. I got my phone back in 2011 from T-Mobile UK and I am now running JB 4.2.2 Revolt JB I9100 and Dorimanx V9.33 as kernel.
My battery is going from 100% to 0% in like 4 hours. Any help would be very much appreciated.
Thanks

Batter drain in 4 hours is not normal. But with heavy usage of 3g/4g it can be. As you said you got heating problems too.
So, first with the battery. Install betterbatterystats from play store. Let the battery drain off completely and charge it to 100 in a go keeping data network/Bluetooth/GPS/WiFi in off mode. Check how much time it's taking to charge it from 0% to 100%. Now discharge it off to 0% and Check the rate of discharge. If it's below 5%/Hour you are safe.
But if it is as you said before 4hours battery backup, there must be some trouble.
These kinds of drastic battery drain happens of many reasons.
1. Poor signal strength.
2. Overloading cpu ( which also cause overheating)
3. Any background running apps which utilizing a bunch a data.
4. Bad kernel (we can pick this out as you tried different kernels.)
5. Defective battery.
Or a last chance
6. A hardware failure.
So inorder to find the root cause behind this problem check each of the possibilities one at a time.
In case of cpu, change the governor and I/o scheduler and see.
In case of background running apps, check whichever programs revising maximum amount of battery.
Hope it helps..

Cheers mate,
I am well aware that custom kernels allow me to overclock it and change governors and i/o and that these kinda settings have a major role on how much battery the device will consume. But as I have never really understood the diferences btw them I for once have never played with the values so I have always left 'em at their default value.
The only real reason I've decided to change to a Custom Rom is to get new versions of the Android OS and to get rid of the hideous TouchWiz skin from Samsung..
I am not living in the UK at the moment as got transfered to Brazil for work and I have been on TIM network and they suck badly so maybe cuz their 3G sucks its whats causing my battery to drain like crazy.
But I will definitely follow your instructions and hopefully I'll get a positive result..
Once again, thank you very much.

[Q] Heavy battery drain issue - help troubleshoot

Of late, I have been having heavy drain of battery on my Atrix 2. I am running JB 4.1.2 (672.300.404.ME865.Retail.en.05). Trying to troubleshoot it (including recalibration) since the last few days without luck.
The symptoms...
- Sudden shut down - Have had 50%+ charge levels. Goes down to 5% and shuts down within minutes. (You can see the random drops in the charge levels in the pic)
- Completely drained out battery charges from above 40% when plugged in & charges to 100% in no time. (that 67% charge in the attachment is within 5 mimutes of power plug in)
Does the battery need a replacement?

Try changing battery... even i had same problem with Custom rom. Battery used to last only for 10 to 12 hours but now its more than 17 hours on JB 4.1.2 leak,,,,...Use stock rom. and remove any unncessesary apps and installl ROM again if u want :good:

How old is your Atrix 2? If over a year then battery surely begins to give lesser performance. Disable any other task killer / memory manager & just let OS do its thing. See if installing Media Scan disable from play helps & do not keep using random chargers, make use of original charger as received with phone. Finally see Better Battery Stats. It is said battery stats should never be wiped but see if it helps you and finally search for Apex's better battery life guide for many handy tips.
I disabled notifications, sync, froze higher wakelock apps & my battery life improved a bit but then it is no fun existing in a bare bones environment.

The phone is just about a year and half old. The drop in battery performance is just too drastic, sometimes it doesn't even last an hour after the charge. Will try to go back to original ROM and see if it improves else will probably have to go for a new battery pack.

Look like a battery problem to me its not the ROM but anyways turn off location services and wifi they are a big battery drainer
Use 2G when u dont need high speed.......
Try this app called Greenify https://play.google.com/store/apps/details?id=com.oasisfeng.greenify
(it helps to reduce wakelocks and improves your battery life)
:laugh: Let me know if it helped (btw chck your battery and see if its defected they are amny ways to chck it read up the forums )

i have the same problem whit any rom of 4.2. when the custom rom shows 5% i change to stock ics rom an that show me 45%

Think mine is clearly a battery issue. Replaced the battery with a new one yesterday and now the phone lasts 6 hrs at least on a single charge.

CM 10.1.3
I couldn't write to developer's forum so I'm asking here.
I've recently firmwared my AT&T A2 CM 10.1.3 and battery drains really fast! The previous build was CM 10.1 (25th of June). I wiped cache and dalvik cache and firmwared CM 10.1.3. At least 3 people report that thie batteries on this ROM drain slow.
What did I do wrong???

Battery life varies so much from user to user that it is impossible to answer your question without A LOT more information.
Go here:
http://forum.xda-developers.com/showthread.php?t=1179809
Download the app and follow the directions in the op. That and reading through that thread itself should tell you everything you need to know about what is using up your battery.
That being said, everyone has different habits and expectations when it comes to their battery. What one person says is good battery life, another will likely say is bad. So just keep in mind that there is not a right or wrong, just what is right or wrong for you.
If I had a dollar for every time I said that, I'd be making money in a very weird way.

Thank you fro your answer. When I used previous version of CM the battery lasted 3 days with minimal using and turning the flight mode at night on.
As long as I installed newer version with JBX kernel the battery lasts 20 hrs max.
Power Tutor says that the most hungry apps are Android System and Kernel

[Q] Battery life with Lollipop ?

Hello all,
I am slowly solving the new challenges Lollipop is causing. I still like it
One quick question: are you getting better battery life than before?
I seem to get worse - as before I used custom power setting (reduced clock speed, reduced fps)
What is your experience? Any tricks to maximize run time?
I seem to get about 5 hours of mixed use (no hardcore gaming; web browsing; reading; simple games)

Quick question for you....
After the Lollipop OTA, did you factory reset?
I didn't at first, and I was getting terrible performance (high memory use, terrible battery life, etc.)
But then I decided to factory reset and start fresh with a "clean" Nvidia Lollipop, and the difference is like night and day.

Battery is the same even after factory reset. There is not such a miracle update giving us more battery. The device will take 10% of your battery in normal conditions (Browsing, youtube, etc) and with Optimized performance. We got a really tin tiny battery, we can't do more than tweaks the OS for best results, but is not that powerful as i wish.

Thank you. I did a factory reset. I was just hoping to see the 30-40% battery life improvement some lollipop reviews spoke about

I'm getting substantially better idle battery life and light usage doesn't drain as bad as on KitKat. The main improvement I've seen is the tablet basically never gets hotter than 90 degrees Fahrenheit.

No issues here. 5 hours SOT with heavy gaming, videos, and browsing. Improved over kit kat. Will get even better once they fix the LTE radio behaviour.

You should try the "shield power control"

[Q] ROM + Kernel for Best Battery Life?

Hey I'm looking for the closest to stock ROM with the best battery life. Im not sure if i should stay stock and rooted (6.0.1) and go with franco kernel or switch to CM 13 (CAF?)...or something else even.
Id say my usage is about average, minimal usage while working, probably less than an hour talk time per day. Maybe 1-2 hours of screen on using various apps (browser, light games, news apps). Generally i make it through a day with about 20-25% left before i goto bed and plug it in to charge every night.
However when i do make more use of it the battery seems to deplete pretty fast. Ideally i would just like better battery life, its the primary reason i havent upgraded the phone yet. I dont need a faster phone, i need one that gets significantly better battery life.
Any recommendations would be great. Thanks

Your mileage will vary greatly depending on usage and what apps you use.
I have personally found that a good kernel is the key to good battery life. I'm a fan of Cataclysm and ElementalX personally.

Best battery life is with stock rom + stock kernel. Before i used custom kernels, but over a week now i have used stock rom with stock kernel and i must say that i get better battery life than before with customs. IMO.
