Dear All
Which is the best radio availble at the moment for battery save? i tried the last released but i found fast battery drain.
thx

It all depends on where you are. Just dont try to flash radio too many time, it is dangerous. If you still want to flash, flash using SD card.

[Q] Battery Drain Since Moving To Stable?

Hey there,
I was using the CM7 nightlies for a while, and the battery life was great. However, it seems like ever since I flashed CM7 Stable my battery life has went down. The part I'm finding odd is that it didn't even last 12 hours today and I barely used the phone (especially in the first 8 hours since I was at work). As well, the battery usage shows Cell Standby and Phone Idle combined using over 85% power, which I've never seen before. I want to say it might be some of my apps, but they're the same ones I've been using. In case it makes a difference, here's my setup:
LauncherPro
Trillian
Clock/Weather widget from Fancy Widget
SetCPU on "conservative" setting
Gmail, Facebook, Messages widgets from LauncherPro
Power Widget
Score Mobile widget
None of my sync settings are really frequent, most are hourly refresh, another is 30 minutes. And since I haven't had this problem before CM7 stable I'm still thinking maybe it's something with the ROM.
What I'd like to know is if I should try to calibrate the battery first. And if that's the case, what is the best method to calibrate the battery so the ROM is reporting it accurately.
Thanks in advance

Anyone have any ideas?

I have been getting the BEST BATTERY LIFE EVER since moving to the latest radio.

wipe the battery stats... look at the forum how to.

Which radio is that?

Always flash at 100%. Then use your phone at least 4 days, as in 2 complete cycles of using until you have to charge it again. Do not change your radio unless you are absolutely confident about the things you are going to do. Chances are you have a custom rom which does not match the radio you are trying to flash, resulting in a expensive ¨presse papier`.

I appreciate the caution, but the current radio I have is the version that Virtuous recommended to update to. Is there a more "Cyanogen-specific" radio?

I got the stock radio and it's working perfectly. 28hours of uptime with ease (and everything on, incl pushmail). No GPS issues, good reception and no static in the background.

when you say use your phone for 4 days (2 completely cycles) until you have to charge it agian... what do you mean exactly? i need to charge mine after like 8 hours...

What I mean is that you should, after you flashed a new rom, drain the battery at least two times and charge it again fully. Or charge at 100%, flash and wipe battery stats after flashing to speed this up a little. Point is, there is no definite daily use. You could (usually not) notice a very small difference in batterydrain after flashing, but be sure it's not because of Bluetooth, Wifi, GPS or some other thing which is accidently turn on. That's why I said to use the phone for 4 days, and 2 complete cycles. I do not use my phone as heavy as you seem to do. Furthermore, I take care not to turn Wifi, Bluetooth or GPS on when I do not need those functions.

Changing ROMs often?

This is a semi general android question... but i have a galaxy nexus... and that's what I'll be paying with...so....
I am currently testing out ROMs... mostly apex and its previous incarnations...
I was wondering if there is any downside to flash ROMs often? Like once or twice a week, as far as longevity of the device or its rank management or " snappiness"?
Thanks for the info!

You will be fine. From what I understand it takes your battery a couple of days to "adjust" to your rom properly and display accurately

and if not you can calibrate your battery using battery calibration.

Hey I am on build 20 or AOKP so I have rebuilt mine at least twenty times but probably a lot more because I have tried ever rom available. I think of it like rebuilding my laptop, I don't think it does any harm at all but over time the device will deteriorate just like any other hardware device.

NAND flash is susceptible to write wear and will degrade over time. Frequent ROM flashing will increase the write rate to the NAND and over time the storage performance will decrease.
I have not measured the impact myself.

what sillow said is what is worrying me mostly...i will probably end up keeping one stable build and only reflashing once a month or something of the nature just to get updates....
I know that hardware performance will deteriorate over time like any other device...the only thing is that i'm in Canada...so...yeah, three year contracts...hehe
i'd like to have my phone survive at least 2+ years comfortably...hehe
minipaolo - do you mean the battery calibration app? i'm using cwm recovery and there is an option to wipe the battery stats from the recovery, which i think is just what the app does, if i'm not mistaken? (other than showing stats, of course...)

There has recently been a google+ post from one of the google developers who said that deleting you're battery stats has no influence whatsoever. Your battery will automatically calibrate itself, so no need to use a special app or delete the stats.
Anyway, good question in the OP. I can imagine it decreases the lifespan, but I can't imagine that it's decreased by a lot -or maybe just wishful thinking-

haha...exactly, let's just hope if there is an impact, that it's quite minimal...

I've been flashing roms ever since I got my first Android phone all the way up to the Galaxy Nexus now. Never had a problem.

Uk OTA UPDATE

hi guys
I downloaded the update but it wont install as im rooted. Does anyone know what the update was for and what it improves?
Also does anyone known if you can circumvent the root issue or is it a case of unrooting and installing

It's for battery improvement that's about it and yes you have to unroot not really worth it for that there's meant to be a big update soon i would wait

Oh really? Cool. Any source?

The real question is will it block root (the big update). Any update that removes root isn't worth it.

If you haven't updated think twice. here is my experience.
After the update my screen no longer goes to full brightness, the indicators and icons still say 100% however the screen has gone from 255 to 238 brightness at full. I think this is one of the ways they increased battery life
Note Lux and other brightness settings have not corrected the problem permanently.

They have increased battery life by having much better thermal controls i.e. the phone doesn't get as hot, one of the ways to keep the phone cool (and therefore indirectly increasing battery life) is to lower the brightness.
Keeping the phone cool was their main aim here, not to increase battery life.

Regardless of the reason my phone was perfect before this change and I had no heat issues or battery problems all was great, if you want to change options like this having an extra setting in the power menu would have been the way to go in my personal opinion.

Painfully bad wifi reception on HTC 10

Hi, I just got a new HTC 10, but I've encountered an issue with it - the wifi signal reception is a pure clown fiesta. My room is fairly far from the router, but even then I managed to get near perfect connection with my ~5 year old Samsung. With my new phone, I can't even open google play most of the time. Same router, nothing changed there
I've googled it up a bit, and some people suggested to force the 2.4Ghz band, but it's already the one I'm on. Do you guys have any other idea what to do?

Can't give feedback on 2.4 but i am on 5 Ghz and that is working fine. It still could perform better in my opinion but it is surely fast enough everywhere in the house to have a solid stable connection.
Did you try 5 Ghz ?

I'm not sure if my router allows that. Tbh I couldn't even find the band settings in the wifi settings - I'm on stock Oreo update :/

Well the 10 isn't very well known by its awesome Wi-Fi reception, it has been a discussion from the beginning but as far as i can see it it should be more than fine in standard conditions.
Another possibility is that it can be better on nougat than oreo but with an S-ON device it involves downgrading firmware by a pretty complicated tutorial (at least if you don't know anything about flashing, fastboot commands, basic android flashing)

Well I've played around with the phone for a bit and found out a different problem - the battery is absolutely pathetic. With data/location on I get under 1 hour of SoT, which is waaaayy less than what I get with my current 5 year old 2600mAh device.
So I figured I'd actually try some of the custom ROM as people seem to like it - is there any 'easy tutorial' out there how to do the whole thing step by step? I've seen some tutorials how to do root, or how to flash, how to install stuff, but never quite all together... Even though I'm very anti-technical type, it seems like it's a last possibility since with this battery, the phone is borderline useless to me

The first 2 video's explain basically how to unlock the bootloader and how to flash TWRP recovery. But check for updated files, the ones used in the video may be outdated by now.

So if I understood it correctly... I must follow these three steps (unlock bootloader, Root the device, install TWRP recovery and "S off"), and after that I just download and install the things that people share on the forums, such as this: https://forum.xda-developers.com/ht...lineageos-16-1-unofficial-builds-pme-t3851614 ?
Also do you (or anyone) have experience with some of the custom roms? Does the battery get significantly better? Right now I lose more than 1% per 1 minute of watching video on youtube which is a bummer

No, only this
Unlock the bootloader
Flash TWRP
You do not need S-OFF specifically and you do not root the device, you give root access to the running OS ! Don't mix that up. A custom rom has root access 99% of the time.
Do NOT expect wonders to your battery, if you get less than 1 hour screen on time either the battery is bad or you have a massive drain on an app. The OS won't likely improve this behavior. So dont get your hopes up that it will be 2 or even 3 hours after flashing just a custom rom.
Getting more battery life is a combination of running the proper custom rom and a custom kernel with usually the according app to customize it. Don't expect it all to be good with one press on a button, this is all pretty advanced.

Hmm I don't really see any app draining it... As for the battery, the phone was apparently checked sometime in 2016 and left in the box ever since... I know it's rather specific technical question, but do you suppose it's possible that the battery degraded so much from just sitting in the box?

Well yes everything at this point can be a possibility, i see many reports lately about bad batteries. I must say mines still oke, i get around 4 hours SOT and it get's me through the day easily without charging it.
In my opinion, 1 hour SOT or less is pretty sure a bad battery and a custom rom and kernel might stretch that but 4 hours you will never reach.

wifi works well at my home on 5ghz and 2.4ghz
usually just use 4g though outside of home network, since im now on unlimited data plan
accubattery is a pretty sweet app.
says my battery is at 77%, which seems about right. I can also get around 3.5-4.5 hours SOT on Nougat crdroid.

Yeah I was warned that battery life is a poor on Oreo update, but I couldn't quite figure out how to avoid the update when setting up the device... Yeah I actually got Accubattery myself, it shows that 1/3 of the battery is gonezo (2,069 MaH out of 3,000) straight out of box so it explains a lot.
I figured I'd try my luck with some of the custom ROM, but since I've never done it before I'm afraid I'm just going to brick my device... Still worth trying I guess :silly:

Nah, bricking is more on an ruu or messing with the aboot.img
Flashing a rom you should be fine. But I understand man.
I'm on AOSP N and getting decent battery with 77% battery, and this is from 80% charge. It's rare I charge above 80%
I've had my phone since release day.

WiFi is nothing to write home about, I gave up on 5ghz and use 2.4ghz as it reaches farther (more stable from 40ft distance to router).
I used to get up to 3hrs expected SOT (70%health) on the original battery per Accubattery, device was new, but sat on a shelf for a couple of years.
With new battery, expected SOT went to 4.5 hrs (100% health). It was worth the pain of opening it up and changing it (I also had to change the charge port, was causing ‘otg_default’ and ‘ohio_wakelock’ wakelocks eating into Sleep mode and reducing SOT indirectly.)
Check wakelocks with Betterbatterystats app, maybe you have similar issue.
