is it possible: Battery saving custom rom

is there anyone who can do this . android style??

the battery saving options currently present in wp7 mango are far superior to anything Android can offer.

What is there to do to save battery? Nothing runs in the background. All bloatware can be uninstalled the second you power on the phone for the first time. I don't see how you can get any more efficient than what Microsoft has tried to do in Mango, or by allowing them to continue optimizing it themselves.

Android has (or allows apps) that can do handy stuff like underclock the processor, turn on/off various services based on your location or time of day, and so on. That'd be nice

This isn't android.

battery life is still poor compared to wp7 and iOS.

like underclock options ect........

Battery saver in Mango already does that. As far as I can tell, it does:
- Disables wireless and bluetooth
- Disables all push data communications and sets mail check time to 30 minutes (for gsm)
- Disables background processes and tweaks kernel for less consumption
- Underclocks the processor ? (not sure about this one)
In this mode, it's superior to any other Android power saving mode I've seen. And you already have it so what exactly are you looking for?

underclock , radios on demand, ect

I'm pretty sure the OS by default under-clocks the CPU where it can.
The only thing I can think of that you could do further is turn the auto screen brightness off, and then turn the screen to the lowest brightness.

i'm curious what versions of wp7 and ios you're comparing to what versions android, and on what devices ?
also, what are the runtimes of these devices ?
specifics might clear the air.
I only have 4 devices to compare myself, g1 @ 32 days without a charge.. g2 with 14 days no charge... nexus 23 days no charge... hd7 with 3 days no charge.

That's on my wishlist too.
I knew I forgot something besides what I've already mentioned
- Screen timeout to 10s
Speaking of battery consumption, one day I forgot to turn up the volume on my Focus. I use data connection daily (mail mostly and few minutes of browsing).
So, by muting the sound (vol 0 of 30), I get more battery at the end of the day with gsm data connection enabled (I receive about 30-40 mails per day). I'd say the difference is about 20-30%.
This could be something worth looking into for the MS folks...

Don't think it underclocks. I hit the battery saver mode pretty much every night.
But I agree with having Microsoft figure out best battery optimization.

Google Nexus 23 days without a charge..... u have gotta be kidding me. The only way it can do that is if you switch it off after charging, use a Windows Phone for 23 days and then boot it up on day 23

i dunno, if the phone can sit there powered on for a week, and still be usable for whatever purpose i'd say it's possible to compare efficiency assuming the battery is similar in mah rating.
otherwise, we'd have to run the same kernel, apps, libraries, and circuit board revision numbers... which isn't possible.
still, open to suggestions and eric1234 to clarify.

i guess it would be called 'idling', but it's powered on, with wifi turned on, checking 1 email account once an hour. i don't have a sim card in it currently. it's just a glorified hd camera/phone/thing for motorcycling currently. and trying new UI's/roms. the g2 slaps it around like a red headed step son. no offense, red headed step children in the room.

[REGISTRY] GPS Settings overhaul

11th DECEMBER 2012 UPDATE:
With the 7.10.8858 WP7.8 ROM on my Lumia 710 (RainbowMod 2.0.1) I can run the enhanced settings posted originally with battery drain held in check.
I assume this is the same with all ROMs from the Dynamics 2.x family, after a few charge cycles for the battery to calibrate.
______________________________________________________________________________________________________________________
Hi all
I've been tinkering with the GPS settings for a long time to try to combat loss of signal and I've found the sweet spot and it seems to improve matters for a range of phones (tested on LG Optimus 7, HTC HD7 and Nokia Lumia 710).
I've now clocked up over 800 miles with these settings and they work brilliantly, even in the "concrete canyons". Give 'em a go (all other settings remain as default):
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\GPS Intermediate Driver\Drivers\GPSOneDevice]
"QOSPerformance"=dword:255
"QOSAccuracy"=dword:3
"PollInterval"=dword:250
"FixMode"=dword:2

good finding. I just got Lumia 900 and use GPS for less then an hour, it lost the signal and cannot recover until I reboot the phone. Maybe this could help.

did you also test this in a city with lots of narrow streets near to another ?
could be a problem because you changed the Accuracy alot

Be aware that the GPS is already one of the biggest battery hogs on the phone, and trying to increase its accuracy is likely to exacerbate the problem.
Also, Lumia 900 owners: unless there's been a breakthough somewhere that I missed, you aren't going to be able to edit your phones' registries. This kind of thing requires, at a minimum, interop-unlock.

I've tried it in a variety of places that fit that description and its been fine. My HDOP is averaging 6-12 most of the time. Its basically requesting as low a degree of scope for varience in accuracy as possible. I tried it on 5 and it was great, 3 is even better. Coupled with polling more often and the top performance figure (255) it basically tells the satellites that this is a priority request for pin-point positioning.

Its swings and roundabouts - you can have patchy lock accuracy and better battery life or great lock accuracy and a bit more battery drain. Since I use it for car navigation and its on charger all the time its acceptable. Whilst on charge in my car and used for navigation it loses about 5% an hour on my Lumia 710. To me, that's acceptable to get a lock I can rely on. If I'm not actively using gps it doesn't impact battery life on my phone.

this values is on my HD2 (GPS working perfectly)
"QOSPerformance"=30
"QOSAccuracy"=50
"PollInterval"=500
"FixMode"=3

Wait, it *loses* battery even while plugged in to charge? That's just messed up... it might be usable while navigating on a charger (although I find the default parameters sufficient for that in almost all cases) but I sure as hell wouldn't want to use it for getting around on foot or something. With that said, an app to quickly toggle the settings between the defaults and the high-accuracy mode may well be worth it.
Oh, one more little misconception: GPS is a totally passive receiver. You aren't telling the satellites anything. In fact, they don't even know that you're there. All that BS you see in movies where a GPS satellite is used to locate something on the ground is just that, pure BS. GPS satellites just orbit the Earth continuously transmitting; it's entirely up to the receivers to listen to those signals and, based on them, determine the receiver's location (relatedly, a signle GPS satellite can't be used to locate anything; you need at least three I think).
I suspect what these parameters are changing is A) how much CPU the phone devotes to getting accurate fixes, B) how much power the phone applies to amplifying the signals and processing out noise, and C) how often the phone makes the effort to compute the location (that's the PollInterval). I have no real idea what the FixMode does, although it may be related to some of the other items somehow.

On original settings all my phone's have had issues at times in cities with getting and maintaining an accurate lock. I have long suspected that the demister wires built into my windscreen were somehow causing problems with GPS reception.
With these settings it works flawlessly. Maybe the thread should be renamed with "for people with demister wires in their windscreen" then.

No doubts, those values improve the location service, but it's draining too much energy, seems that even with the phone in charge, using Navigon will be possible only during few minutes!!! Not fair...

I have happily used Navigon with all live services active for more than 5 hours driving with these settings and on charge in the car. From a full battery I still have around 75% charge left. I'm quite happy with those stats if it means I can rely on locks.
I have the settings permanently set and in day to day use (without prolonged GPS use) my battery still lasts 2 days.

"Relaxed" settings - drain reduced
For those concerned with battery drain, I have tried "relaxed" settings that on an hour of use (all the testing time I had, currently) in an city driving environment allow the handset to charge in car without battery charge losses beyond what the charger is supplying and still give pretty decent results:
Fixmode: 2
PollInterval: 500
QOSAccuracy: 100
QOSPerformance: 10
HDOP varied between 8 and 15 with these settings.
I don't know how much power these settings will pull when not on charge as have not had chance to do any extended testing but expect it to be only marginally more than stock, but better results.

Ok, lots of testing later (200 miles and counting) and the relaxed settings pull no more juice than stock settings, but give markedly better lock stability. Try it and see.

[Q] How is battery life compared to G3? (g3 owner willing to buy g4)

So, title self explain. I have G3 and want to ask to someone who made the upgrade from G3 to G4. Is the battery about the same as G3 or is better?

i had G3 and recently i bought G4 not much difference but lets say the G4 win with alittle bit but from my opinion i didnt see abig difference

advice :Stay away from G4--- this device has too many hardware issues

Don't feed the troll :good:

i was planning to buy the G4, so i looked at some reviews. GSMArena said that the battery life on the G4 is a downgrade from the G3.
The Endurance rating worked out to 54 hours, 9 hours less than the G3. The issue was with the high standby power draw, which puts a strain on the battery even when you're not using the phone. The other disappointment was the talk time, which couldn't reach 17 hours - an 8 hour drop from the G3.
We reran the tests several times and kept getting the same results.
Anyway, the web browsing time was pretty good - nothing spectacular, but good. It also marks the only improvement since the G3 as the video playback is below average for the flagship class.

ok. where does it make a direct comparison to the G3. the video is kind of hard to follow. Unless he has both phones in the same video and do a same battery test, you can't really compare the g4 to g3 with this video. the OP just has to decide which source he deems more reliable.

yes because this is a difficult subject so keep a note when he talks of the sot's under different conditions.
Had to watch it a couple of times but i got it in the end. See the comments too.
What is your expectation of sot/runtime ? How much do you get with your curent device ? what is your current device.

There is no difference between G3 and G4 for battery life max i can get 4 and half hours for battery life and minimum only almost 3 hours SOT. Maybe if next LG device is like this battery life i need to change to another brand

Yeah my experience in two days....Touchscreen issues untill i updated to V10C which fixes the touchscreen issue but decreases battery life to the extent where u can literally notice it drop before your eyes. The power saving used to work fine before v10c now even tho i turn it on immediately it wont kick in untill battery reaches 15% ( u will know when its on because the statusbar will change its color to red)...... And yes the back buttons are loose and feel wobbly. There is a pink shade in my front camera when there is sunlight in the background....ummm what else......i am damn sure even the cheap chinese phones coming out will be better than this piece of junk. I shud never have bought it

Dont expect anything crash hot from the battery performance. It is nothing like what i expected. If you want good battery life go with samsung s6 or even better the sony xperia phones. Xperia has best battery life. So G4 wont do you any good with battery life

3h sot, lots of complaining, 4h+Sot less complaining or it goes silent. Seen this a few times now. That is what surprised me. Until you realise that people find 8h run time too short but once it gets into 12-14h+ its ok. Its the standby time that is more important.

I currently have the nexus 4 and i think the most screen on-time i can get before my phone dies is 3 hours, but usually it's in the low to mid 2 hour range before i have to run to the charger. But the phone never last more than like 12 hour of usage (or a 8 hour workshift+ work traffic) as i constantly surf the web, music, and always checking my phone.
I want something like xperia z3 compact or note 4 battery life, but those phones have some things i don't really like. With the G4, i do plan on buying those high capacity battery (like mugen, hyperion, etc..) if the phone does fall below my expectation.

How bright do you like your screen. if you can manage with less brightness ie 30-50% you can add an hour of sot.
for reference, 3-4h SOT on data and 4-5h sot on wifi only with 65-70 brightness. mixed use means somewhere in between, 4h sot. high brightness means low to mid 3h, less brightness 4-5h.
sot/run times you can expect 3h /9h, 4h/12h, 5h/14+h is normal with stock.
Are these figures you can live with ? xperias & note 4 will give you an extra hour sot on top. that extra hour means 2-4h longer run time.
you dont need to carry those bulky batteries unless your phone absolutely needs to be on, just swap the battery out in a couple of minutes.. Not hot swap, have to power down.
How important is bootloader unlock and roms for you ? some people are forced to stick with original and forego firmware updates to preserve bootloader unlock. this means if any improvements are made in subsequent updates they can't use them and are stuck with whatever bugs are there in the older firmware. Stuck with bugs and waiting for roms can be frustrating.
For some one used to nexus 4 being able to flash anything and everything, G4 might seem a bit boring for you, Nexus 5x ? you dont care for replaceable battery or sd card. just get the biggest onboard memory possible

Yep all wifi, don't have a data plan . wifi signal varies to maximum signal to no signal at all lol. But i do turn on airplane mode when i'm on the train for example. My brightness is set to adaptive brightnes on @ 50%ish
I'm actually avoiding the nexus line in the future lol since i really want sd card slot and removable battery (and good/excellent battery life), usb OTG (particularly usb audio out), and a device that can officially unlock bootloader like the g4 H815. and to be honest, stock android ui is sometimes boring and it never has features u see on like xperia, htc, or samsung devices. And I can just do all my flashing needs on my Nexus 4 when the habit kicks in lol. Overall, on my next phone, i just want options and upgrade/replacement possibility

I'm actually avoiding the nexus line in the future lol since i really want sd card slot and removable battery (and good/excellent battery life), usb OTG (particularly usb audio out), and a device that can officially unlock bootloader like the g4 H815. and to be honest, stock android ui is sometimes boring and it never has features u see on like xperia, htc, or samsung devices. And I can just do all my flashing needs on my Nexus 4 when the habit kicks in lol. Overall, on my next phone, i just want options and upgrade/replacement possibility

Then you can expect a 4-5h sot/12-14h run time with normal use. Good enough ?
web browsing won't eat up much battery, its push notifications and constant syncs over weak signal that do it faster.

IMO the g3 was garbage...i had 2 that had emmc failures and all 3 i had overheating issues...battery sucked...only pro was there was a good bit of development...i love my g4...only device i miss over my g4 is my g2...battery life is great with minimal tweaks and greenify...my last run was 5 h 2m sot and 47.5 standby...h81110n

(Important) Checking a new G4 for issues?

hello everyone
I'll be buying a dual-sim G4 either today or tomorrow. The issue is that I'll only be given 7 days checking and replacement warranty which is worrisome since the product price is quite high. So, I'll need all your inputs on how can I best check the product for any issues so I may return/exchange it within the short warranty period. Also, since I'll be leaving for a job outside my country within 2-3 weeks, I need to make sure everything is in working order as I'll be at a place where there would be no repair shops etc.

please, can someone kindly help me with this...

You cannot check for issues while installing any app i believe. Yes, you can install heavy games and play them, use The phone as much as you can to check about it.
Do remember to check volume buttons properly, camera and OIS working fine or not, any kind of lag report it here. If its common, you are good to go

Check the multitouch test using antutu benchmark.

Go to 277634#*# dialer mode and go to lcd test under svc menu.
Then go to device test> MT> then it will boot into mini os where you will get plenty of tests available to test g4.

-got the cellfone yesterday, two issues till now. battery seems to be draining very fast + the screen gets hot.
-antutu score is 62164
-have already taken pictures and videos from it - camera result seems ok, any idea how can I check it extensively? not too sure how to use the manual function :S

Can you please elaborate? Were you on 4G or 3G? How many hours phone was used. What all things you did (heavy games or light games? too much calls? GPS settings? Wifi and 3G/4G usage). Apart from it, how was the cell reception? Low cell network reception leads to heavy battery drain. Also, I have noticed heavy battery drain on dual SIM.

hi... I noticed that when I use the camera app the phone heats up, so much that its hard to make a call with it. Games, well..haven't install any yet - not much into games but could you please recommend a few so I can check my phone... wifi was ON...
am not really sure how to check the phone extensively, only 2 days left of 7 days warranty...and I don't know what or how to check it since am also in too much pain because of root canal of my 7 teeth :crying:

take your money back and wait for g5 or other new generation phones.

was playing with the camera today, when using flash its dead-slow and the result is s***. even my nokia 808 is faster when used with flash.

S20 Exynos - Very poor battery <3hrs SOT

Hey there
Purchased a new S20 Exynos 3 weeks ago. Since then battery life has been awful... even below what users report on the forum (4-6 hours SOT ranges).
I barely get 3.5 hours at best with minimal usage in a day: whatsapp, calls, emails, social media - NO gaming, gps, video calls...
This has been the same under OneUI 2.5 or now 3.0 for the past week
I have tried everything:
debloated a lot of stuff
wiped the phone with factory reset, did not restore with smart switch
60hz only, dark mode
location off, all device or wifi scanning features off
lots of apps in sleep and deep sleep lists
took the phone to samsung service to verify battery was functioning normally
I'm sharing screenshots of GSAM and BBS - please help me understand what is going on, i'm not able to make sense of the stats
I really want to love this new phone.... but 3hrs a day for a work phone + samsung service being a complete waste of time is not helping me...
Many, many thanks for your help

Why is it showing LTE2?
Maybe put your sim in slot 1?
Are you in a poor reception area? Your phone signals are good but still can't be trusted.

I have 2 sim cards in the phone. The one I'm using now is in slot 2
I even switched off sim 1 in sim cards manager because it was draining battery. I need to switch it back on anytime I want to receive SMS or call
Yet another feature that made me buy the phone and I end up deactivating....

Any other idea where I should deep dive? Do you see any app draining the battery or weird wakelock?
I need to get at least 6hrs SOT on basic usage

That's poor SOT even for a Exynos device. Based on the info you've shared it would seem your phone is defective. If it was purchased locally you should ask the seller to exchange it. If a full factory reset doesn't help I don't know of any other settings or modifications you haven't already tried.

At this point I can only suggest you to try using only single sim via slot 1 and observe the difference.
Also can you post gsam signal graph like mine.View attachment 5155689

My device is S20+ on 3.0
60HZ, WQHD enabled and I'm getting 10H SOT.

Thanks guys for your help. Really appreciate it
Samsung doesn't want to replace the device. They have tested it for 24 hours in idle and told me the standby battery drain is normal.
This is insane. I've never seen so poor customer service, I miss apple so bad...
I've switched my sim to slot 1, that's a bummer since I'll need to play around with sims every time I travel...
My reception should be good as well.

Guys do you have by any chance a contact at Samsung top management to share in DM?
I'm dealing with India customer service this is appaling.... [email protected] supposed to be case manager what a joke
I've been fighting with them for 3 weeks it is driving me insane.
I'm talking to a lawyer today to open a law suit, probably a class action law suit, against Samsung advertising high performance but selling poor quality handsets equiped with Exynos chipset

No doubt you're level of frustration is rightfully extreme but I'm pretty sure pursuing a class action lawsuit to remedy the issue isn't your best option. I'm not an attorney but have years of experience as a lawfirm administrator. Not too many attorneys are capable enough or willing to invest the required time, resources and money to initiate that action. Having your attorney contact Samsung in writing may be the best option if he/she will do so at a reasonable cost.

Yes that's actually the plan
Given Samsung's commitment to customer satisfaction I doubt anything will come out of it
Will take further actions when necessary
In the meantime if anybody still have ideas on how to investigate further / solve the issue with my phone (assuming it's not hardware issue and Samsung hiding it from me).... happy to look into it

Latest developments:
Samsung "top" customer support team has arrange a pick up to take the phone to service again tomorrow
If they tell me everything is fine again i'm gonna lose my **** - nothing is fine with a 3 hours battery life phone that cost me $700

How the havk you achieved that???
Are we talking exynos or snapdragon?

i've never seen anything like samsung customer support in my life
5 hours on the phone with them in 2 days, 2 back and forths to service center...
They are still telling me that 3 hours screen on time is perfectly normal on my handset and refuse any refund or replacement
"we have done 1 hour of youtube and the battery dropped by 35% because youtube is hardcore. See that's good"
wait... what?
plus i've never opened youtube on my phone what's this test about
Pure insanity
I'm going ahead with opening a class action law suit. DM if interested in joining
it will be shared on social media as well and widely online

Exynos.
No gaming, Just browsing and little bit of youtube.
Maybe bcoz of indoor usage. Brightness is 40-45%

Hey guys why instead of being proud of managing to tweak a $700 phone to make it usable
we just tackled the core issue and stopped buying crappy exynos samsung and make them understand they cannot fool customers
i start to understand why you keep buying if this is just a game to you

Well, Indians voted with wallet.
Due to poor sales in India, S20+ came down to 700$, bcoz of ezorbitant prices on top of selling Ecynos crap.

I have an Exynos S20 and have been having similar battery life issues since FW BTIB and BTJ3, I think I have finally tracked it down to some weird 5GHz Wi-Fi problem with FWs after the August update.
Someone mentioned putting the phone on Airplane overnight which I've never done, so I did after fully charging it and I was thrilled to see the battery dropped by only a few % in 10hrs which was great. In the morning I switched Airplane off back at my desk which is close to the WAP and the battery life seemed really good.
After a week or so of checking with Airplane On/Off and switching between 2.4GHz and 5GHz, I suspect that if the 5GHz signal isn't strong enough the phone is trying very hard to maintain the connection. Looking at your battery stats it shows Wi-Fi 86% battery so this could indicate a similar issue.
Switching to 2.4GHz seems to have greatly helped my battery life. Right now the battery has dropped 38% in 42h13m, with 42m of calls and 21m of SOT. Accubattery still thinks my full charge SOT is 2h30m but that's calculated on 10 sessions and I'm hoping that it might improve over the next few weeks. Still, it's far short of what Accubattery reported about a month after buying the phone (over 10hrs).
If I desperately need 5GHz speed I can just manually switch it, do the uploads, then switch it back to 2.4GHz.

I've sold the S20 and going back to iphone or pixel
worst phone i've ever had in hands
Legal action against Samsung is ongoing - their customer service has been appaling, including talking to their top management in India through my lawyer.
All in all a very bad phone, poor company, 0% customer centricity
