Memory and Battery ... what do you get?

Apparently, the battery life and the low internal memory are some major drawbacks of this otherwise great handset, so I though of putting up some experiences of what users report from their experiences with internal memory and battery life.
(After installing all programs and under normal usage)
ROM:
System 260MB => 32MB free
Data: 150MB =>32.7 free
Strategy: rooted, uninstalled htc stuff.
Battery Life:
24-36 hours
Remarks:
I feel the battery behaves rather strange, think there is definitively room for improvement. Some days, it hardly uses 5% over 12 hours!! Then, on others, without touching it, it looses over 50%!!
I am currently playing around with the Network settings and will see what I find.
Underclocking on demand should further alleviate the problem I hope!
With the original WF I easily got 4-5 days and the battery is only marginally smaller so should be possible to get closer to this range

Here my results:
About 50 MB free of ROM.
About 100 MB free of RAM.
Stock ROM, S-ON (waiting for htc unlock and cyanogenmod)
Battery lasts under normal usage 2 days, light usage 3 days. (When i sleep phone is in fly mode and there's no battery drain)
Normal usage: little browsing, messaging, mailing, music listening, checking news and weather, maybe a phone call.
Light usage: messaging, mailing, a bit music listening, calendar checking, very very little browsing
The biggest battery drain is the screen, especially when playing games (15 minutes dragon fly gives 10 % battery drain) and browsing, market checking/updating.

Everything stock:
free ROM: 47
free RAM: 122
Around 2 days battery use if I don't play too much Airport Mania 2, or else 10 minutes play equals minus 5% battery

UPDATE:
I changed some settings to maximize battery performance, notable
Location => Disable "Use Wireless Networks" (battery eater!!)
Wifi&Networks: Mobile Network Settings:
Network Mode: GSM only (OK I don'T need the fast one)
Enable Always-On: DISABLED
Plus I set it on Flight Mode during night (I used Gentle Alarm to do it before, but apparently there is a bug where it makes it consume engergy nevertheless so do it manually now for the moment)
Results:
For now, 3-4 days!
Will continue trying out (but now it will take a week or two to finish some cycles ;-) )

RAM : 241 free / 160 used
ROM : 70 free / 80 used
Cyanogenmod 7 / 1500mAh HD7 battery
1,5-2 days with fully wifi opened.

Sure you can kill 3G, WiFi etc but then why have smartphone and dumb it down?
Here are a few battery saving tips I've learned from owning a GSM Hero and Desire HD (my gf has WFS which is why I'm lurking here... just ordered a XTC Clip for it).
Unfortunately when the green light says you're phone is fully charged this isn't always the case. The battery is likely to be mis-reporting its capacity and % used, this can cause your phone to die when the battery still has remaining charge. So, we're going to fix that.
Assuming you have already rooted your phone, download Battery Calibration tool and CurrentWidget.
Place a CurrentWidget widget on your home screen and charge your phone until the widget says 0mA. This means it has reached fully capacity.
Once it hits 0mA on the widget, open Battery Calibration and wipe battery stats.
Reboot your phone whilst still plugged in and upon reboot it will recreate a new battery stats file, however now it will know the battery's max capacity and will correctly report battery % used.
I do this about twice a week. Maybe once a month I will also let it completely die and then fully recharge whilst off, before powering on and repeating the above steps.
Other things you can do to increase battery life are:
Change the sync interval of apps like Facebook, Weather etc. I usually set most things to every 3 or 4 hours, with Flickr only being once a day.
Don't run the screen at full brightness if you don't need it. On my DHD I find 40% to be best for most conditions, with only really bright sun making it hard to read... in which case I bump it up to around 75%. Auto-brightness if ok but it tends to be on the bright side on most Sense ROMs so hopefully someone will work out a way to tweak the values for WFS. I had a play about with custom values on DHD but after testing for a while I still prefer to control it manually. It's a personal thing though.
Remove crap you don't need. Stocks, News, eReader, Twitter etc are always the first to go when I install a new ROM. I use Root Explorer to delete them but there are various ways to do this including Titanium Back-up or by using ADB. You can find everything in /data/app & /system/app. Just be sure to do a nandroid backup in case you delete any system critical apks.
Change Wifi sleep policy to Never.
Limit your homescreen widgets to only ones you really need. Having 7 screens packed with widgets and apps will cause battery drain.
Turn off Power Saving mode. I tend to find it doesn't really help and just makes your phone quite useless when you hit the pre-set % where it activates.
Never use Task Killers. This link gives an excellent explanation.
Finally, wait in hope for an overclocked and undervolted kernel, different radios and custom auto-brightness values
If I can think of anything else I'll post it here

don´t know why so mutch people get worried about the battery. for me the only thing that counts is that the battry takes me over the day. i mean i go out an seven am and get bat at 5pm, so thats the time i need my battery to hold. maybe i need some backup to get until 22 pm and everything is alright.
for me i doesnt matter if i´ve to recarge after one day

Yeah, for some people it can become a bit of an obsession. However, it still think it's worth taking a few simple steps to get the best out of your device

For some people 8 hours between charges is fine. For me, I like a phone that can run for 8 hours between charges, but also run for 48 hours between charges (without having to go to dead mode by turning on airplane). I go camping, stay the night someplace else, forget my charger while going on a trip or just want the freedom of not having to find an outlet and drag my charger with me if I want to have a phone run for more than 8 hours. So I get off work, change my clothing and run out the door to my after-work sporting event, then head out for a few beers afterwards with the team and I barely have enough juice left to call my wife or check on a few game scores.
It's important. Not having it be important means your phone is running your life or you just always have the same routine, which is fine for you maybe but I like to head out.

About 7 hours running CM 7. Battery life is very bad at the moment.

CleanRom 5 battery

Hi,
This question is for anyone using the latest CleanRom on their Note II. Just wondering if your average battery drain is around 4-5%/h. I use BetteryBatteryStats. I also check the Battery section under Settings. The most battery life I have been able to get is 12 - 15 h with 1-2h screen time. At this point, the battery is at less than 10%. Is this normal ? I thought I remembered getting better life from older versions of CleanRom. I know these numbers are never achievable on any AOSP rom that I have tried. Just wanted to see what everyone's experience is with battery life. Just post any thoughts!
Thanks for your feedback! I appreciate your time!

Just like anyone else, it all depends on what kernel you're on and what apps you have wakelocking. I've been using Clean 5.0 as my daily for months and the battery life lasts me throughout the day until I need to sleep at which point I plug in... but sometimes, I'm running into fast battery drain due to some apps going nuts on me or when Bluetooth is trying to link from a long distance (where the phone would heat up and drain like mad... btw this only happened to me twice in many months). After a reboot, it usually clears up and after a recharge, I'm back to 14 hours with 20% left at night. I'm not one to be anal about my battery drain if it lasts me until I sleep (because I have NEVER had a smartphone that would last me that long without plugging in... in fact, barely half the day would be when my device would need to be fed).
I'm using Perseus' latest with a few screen tweaks, no CPU or power tweaks, using Facebook constantly, Pulse, SMS/MMS, camera throughout the day, Next 3D launcher with all the fun animations running, YouTube, Pandora when driving (so my Bluetooth is on constantly)... let's just say I'm a heavy user. When my kids get a hold of my device, they run a bunch of games and drain around 10% by the time I get it back.
I am happy with the battery life on my Clean Rom 5.0/Perseus Note II. I won't fuss about it as long as it lasts longer than half the day because that is what I was used before upgrading.

4% drain I'm just 7min?....

I barely got this tablet yesterday and already seeing fast battery drain. I don't have that much apps/games. I rooted it today in the afternoon but I don't think it will drain the battery.... What's the deal here?

This is my 10.1

There's always an initial drain that is rather fast due to the fact that the charging is not perfectly optimized, notably while it's new. Even though it says 100% it's most likely not the fact. On the other hand due to the large screen the screen uses a lot of power. When using Cyanogen for maybe 20-30 min/day I'm still at 97% the next morning w/o charging. But, I use a lot of mods and settings trying to optimize battery usage. Once you get used to the device and start experimenting with ROM's, settings, mods I'm sure you will find a way to optimize it to your flavor.

The tablet has to scan all directories for media.
Here are some really good tips. You can also shut off a lot of samsung bloatware. I have probably 50 things shut off along with below tips I get amazing battery life and never any lag. Not a fan of magazine touchwiz so using nova and couldn't be happier.
http://forum.xda-developers.com/showthread.php?t=2782239

For a new device, you need to cycle the battery to about 10%, then fully charge, to set the battery meter "high" and "low" flags (some call this "calibrating the battery meter"), before you can expect the battery meter readings to be anywhere accurate.

Battery Draining very fast - Hardware issue or software ?? help me please :)

Hi all,
So i got a HTC 10 UAE edition from a guy two days before. He was selling it at a reasonable price and i bought it from him.
The battery was draining quite fast and i thought it might be a software issue and i installed venom rom, but problem still existed, so i turned back to stock 2.41.401.41 (Which was very hard though) .
Still the battery is draining so fast. The charger came with the phone( Quick charger ) was also not working and now i'm facing the phone's battery is draining so fast. I'm very confused whether that guy have cheated me or not. If this is a hardware issue i think i have to contact that guy soon.
adb battery stat gave me 2580mah full charge capacity and here, i'm attaching the GSAM battery logs.
Please help me on this
Thanks
Edit: Since the original charger isnt working, im using a oppo 5v- 1A charger, is dat matters on battery drain?

Mine was doing the same as yours, quick charge also stopped working. I changed the cable and it solved it for a few weeks, but the drain started again and quick charge stopped again. Tried ruu etc but no luck. I've sent mine in for repair under warranty and should get it back Monday. My guess is either the charging port is faulty or motherboard but will find out next week.

I was having the exact same problem. I downloaded an app called Lspeed (It's also on the playstore) and did some tweaking in that app as well as used the Enable doze for GMS Magisk Module and now my kernel and android system are on par with each other as far as battery drain goes. Not sure why there are only a handful of people that experience this problem but i'll edit this post with screens of my lspeed config if you want to give that a go!
Edit: Config uploaded. Some of those options are personal preference but take a look around and test it out. What you'll most likely want is to enable the light doze optimization and disable the debugging. That will most likely help in your situation.

Very strange, I'm experiencing this issue too, always receive around 2-3hrs of screen on with very high kernel use during standby. Tried flashing Leedroid, Element X to no avail.

I'm currently running on pure stock. Will try this method soon. How was your battery standby before doing the tweak ?

Have you tried wiping cache? Mine drains fast depending on the load, which is usually pretty heavy daily. Plus, I don't dim my screen much. Never knew the advice command for battery. I gotta try that.
Stock Rom

Okay, so I got fed up with the battery life I've been getting and have looked more into it, I've managed to reclaim a lot of the longevity I had before updating to Nougat without hampering UI fluidity. For reference, I'm using Leedroid 3.9 with Element X v1.08 and was getting around 2hrs screen on, android system and kernel had the highest usage under GSam.
bilibox has the right idea, my idle drain was very high, L speed and Greenify both have options to enable a more aggressive Doze which worked pretty well, I lose ~10% battery overnight vs a shocking 20-30% before. I still felt battery drain was too high when active, I combined ivicask's PNP mod (balanced) with some little governor tweaks in EX Kernel manager, basically, I'm using interactive on the little cluster and elementx governor on the big cluster (which tends to be slightly more conservative in my uses). I also set min performance to 0% and downclocked the big cluster to 2Ghz, I'm focusing on these cores since they were draining a lot of power in my case.
It's not a super extensive list of tweaks nor something we haven't seen before, but I manage around 3.5hrs of screen on now which gets me through the day. Before I would have to top up around early afternoon, the phone is also really smooth and I'm happy with how everything is running. I hope this helps some people out!

Still its bad that a 3000mah battery with a smaller screen compared to other flagships giving a very low battery backup just because of software bug. From reviews, i can see that MM is giving fine SoT as well as standby. One thing i really cant is the standby. I cant even go out for a day trip. The battery will die in just 10-12hrs even on standby.

That's unfortunate to hear, my battery life is pretty much in line with my friend's S7 now, newer devices can get away with larger displays because the 835 is a bit more efficient.

I restore my phone and did all updates again. My battery still seems to drain very quick .in an hour with some navigation, and little screen use It went from 20% to 1 percent.
I've taken excellent care of my HTC. Before this, I had HTC 8 and loved it, until right at the 2-year mark, a small area of the screen stopped working.
This is the second time I` experience this, and sadly there won't be a third., especially after new HTC removed the headphone jack like the iPhone ... RIP HTC

Well to be honest the past couple days were to weird to me usually i get 5 - 6 SOA over 13 hours
now i get 3:30 - 4 SOA over 13 hours, same usage, and i have noticed that google service consume most of the power, i have installed doze program and kept my eye on GSM battery Monitor, after all the google service kept the kernal wake up for a long time, and keep running the hardware on the full abilities

I unistalled Gsam battery monitor and kernel usage is back to normal...

I have uninstalled ForceDoze and Gsam Bettery this morning but still feeling that there is something wrong, i might do some battery calibration on my free time, because i charge my phone only for 90% and it did not get lower than 20% i feel like i am losing the battery capacity

Was having the same issue, and had been searching for weeks to try and solve this. Tried rooting, factory resets, ROMs, everything.
For me the issue was Google Sync, in particular Contacts and People syncing. I disabled those and everything is back to normal. There was a program called Google Contacts Sync (Apps > Show System > Google Contacts Sync). I cleared the data on that, and then went into Accounts and Sync and turned everything off. That fixed the battery drain. I have tried turning back on Gmail, Keep and a few others and still have great battery.

I have the same issue and I don't know how to fix it. Please help

Question Sensors question about battery drain

Hello guys,
im on stock ROM 12.5.3.0 global and the battery life has been a hit and miss on this phone. Some days 9hrs Sot and other days 4-5hr. Ive been trying to locate the culprit as i have like 2%/h drain when idle and that is killing me(12% overnight in 7 hrs). I dont want to start the flashing custom roms game as im sattisfied with the rom for my needs.
Installing BBS i have sar_detector on phone service sensor having the phone awake for 15hr out of 15 meaning it is on all the time(no clue what this is even after googling). And ofcourse sns_smd on play services for 11hrs having wakelocks.
and most importantly phone awake for 1hr40 while sleeping. ill try charging it full and check discharge overnight but still its a pain.

Are you using Always On Display? You could install AccuBattery, give it Usage Access, and check if it gives you useful data after a period.
It could also be that Double-Tap to Wake or Fingerprint for Lockscreen perhaps use battery, but I don't know how much. Just a speculation. For me battery life is very acceptable, and I even use a Live Wallpaper. ^^
But then, everyone has a different line where they say "acceptable".

I tried disabling them last night. Got better still i think this phone can do more. Sar_detector is being used 24/7 and i cant find a workaround. The battery life is good tbh and it gets me through the day easily. But why not use it like its meant to. Anw i will wait the new update should be coming anyday.
