... and I just LOVE the Diamond. I always thought the Diamond's just a VGA version of the Touch with GPS built in, and hesitated for a while before I decided to go for the upgrade. Almost a month since the upgrade and I can't even imagine myself going back to the Touch.
I love the Diamond for ...
- beautiful VGA screen
- great form factor, fits perfectly in hand or pocket
- 3.5G is FAST ... especially considering I'm coming from a EDGE machine
- The 535MHz processor may be under-rated when running the bad ass TF3D2 interface, but its speed advantage shows in other apps say, like TomTom when alternative route calculation is required
That said, on the other hand ...
- battery life sucks. This is the first phone since ... man ... the Nokia 6190?! when I actually carry a spare battery with me. I setup the Diamond to check email once every 30 min, and keep it to EDGE for email, use 3.5G only with Opera, do very little web browsing, and my battery still can't make it through a 10 hrs day without giving me low battery warning before I get home.
- Compared to the Touch, which had Talk / End / Camera buttons on top of the D-pad, the Diamond loses yet another hard button in the camera button. I use AEB+ to get more functionality out of my hard buttons, but still I wish there's at least the camera button. OTOH, I don't know about others, but I almost NEVER use the back button. I thought it'd be somewhat useful if it gets you back to the last webpage when browsing the web ... but it doesn't. It gets you back to the last app. Worse, the Home and Back buttons cannot be remapped, or controlled by AEB+.
- The Diamond looks stunning with the piano black finish but the whole phone is a finger print magnet. I think I'm developing an anxiety disorder rubbing and cleaning my phone every chance I get these days.
- The phone heats up quite a bit after a number of resets, or after browsing the web for a while. It gets hot enough I wonder if I'd burn myself leaving it in the jeans pocket.
- The combination of heating up and poor battery life makes it a BAD navigator. If I use turn GPS on and leave the phone running TomTom with screen turned on all the times, the battery hits low battery level within an hour. However, if I plug the charger in, the battery overheats (40C or higher) within 30 min to a point either it stops charging, or resets itself.
All in all, I love my new phone! I think it's a great phone, and most of the shortcomings don't bug me much ... but it'd be great if the battery life and the last point about using it as GPS can get addressed.
Any suggestion?
little info, you can remap the back button with aeb+ the button is called "ok" in aeb+, if i remember correctly.
only the home button cannot be remaped..
Also update your Radio. My battery used to be exactly like how you mentioned until i updated it to the Radio v1.13.25.24 (Blackstone) found here:
http://forum.xda-developers.com/showthread.php?t=470306
Make sure you read the instructions of updating the Radio VERY CAREFULLY or you'll brick it.
Since updating the Radio ive noticed a significant improvement not only in battery life but also other things like my phone connects to 3G faster and also my TomTom gets a fix within 10-20 seconds. (before it was more like sitting there for 1-2 minutes before getting a fix).
I also recently upgraded from my beloved S710 to this one since the S710's display broke after it fell out of my pocket.
Being used to the S710's great battery life, the TD was surely a bit disappointing. Apart from that, it really is a cool device.
Regarding TomTom take a look at this thread: http://forum.xda-developers.com/archive/index.php/t-412321.html . It describes how to reenable the dim feature. Unfortunately, TomTom doesn't allow the background light to fully switch off but at least dimming it enhances battery life.
I tried one or two radios and made the best experiences with v1.00.25.05 using T-Mobile (Germany). Fast GPS fix and stable signal, good battery life, great voice quality.
To enhance battery life, I also disabled 3G and used all the other tweaks of Advanced Config Tool. Bluetooth seems to be a battery drainer, so I only use it for ActiveSync.
Having BT/WiFi deactivated, my battery lasts about 3-4 days with medium usage. When listening to music or navigating, much shorter.
Did you condition your battery by fully unloading and reloading it several times?
I generally knows how to flash stuff, use xposed, and whatnot. But I've never really done anything unified to focus on extreme battery saving. I am hoping to be able to switch profiles or something like that so I can keep the phone running on the lowest power possible but still be available for me to wake up to higher power for camera, gps, and messaging uses. The reason for this use case is because I will be hiking half of the Appalachian Trail this summer from Harper Ferry, WVA to Springer Mountain, GA, a total of roughly 1023 miles. Being able to stretch my battery as much as possible without actually enabling airplane mode or turning it off would be extremely helpful. I'm deaf so I cannot just simply borrow anybody else phone to call family. So I must be able to use my current phone for many different functions, including communication.
I do want to be able to use my phone as a primarily social media and messaging device. I have a wordpress blog that I'm trying to get in the habit of updating more often. I also have Instagram, Facebook, and the like. I will be bringing a pocket camera with me but I still want to be able to use my phone to snap pics for easy sharing to Instagram (it will autopost to both Facebook and Wordpress). One of my concern about the camera app is because I know that some ROMs have had issues with the camera's performance after a little while. Being on the trail for about 2 and half month, I won't have any opportunity to fix up my phone. Hence why I want to start testing thing out right now and have about a month or two to go before the actual hike.
GPS is obviously going to be vital. I have a guidebook with me that should covers everything and I almost never ever lose my cardinal direction so I'm not too worried about getting lost. But some GPS access could help just in case I need to figure out exactly how far I've missed a turn or how much I have left to go for the day. Plus it would be nice to have in case of emergency.
I do need bluetooth though. I have a Pebble watch that would be useful for me on the trail, I think. And I will be using a folding bluetooth keyboard on the trail too.
I remember once having Cyanogenmod on an old phone of mine with the ability to extremely underclock. It was incredibly laggy but I was able to create a shortcut to the clocking page so I could switch to a higher speed as I needed it. I'm hoping to be able to do the same with my Verizon's Nexus 6.
Anyway, I'm hoping for any input on which ROM, kernel, etc... would be recommended for setting up the absolute best battery saving and be able to switch the functionality high or low as I needs it. Thanks for any input.

I know that this doesn't exactly answer the question you asked. And I've only owned my N6 since September, and despite flashing everything under the sun with my older devices, I have yet to leave stock on the 6.
That said, are you considering auxiliary batteries (some will give you about 3-4 full charges and are the size of a deck of cards) and possibly solar arrays to top them off? I would consider hanging one from the top of my pack during the day and taking my rests near clearings for direct sunlight. And if you're really looking to stretch your battery, but don't want to run in flight mode, I would consider leaving the BT devices home and maintaining a 2g connection while hiking, only switching to higher power radios when you need to upload images. Remember, in fringe areas, the higher power radios are going to use exponentially more power than when they have a solid signal. And the 2g radio has better reception in fringe areas, besides. Personally, I would use flight mode while sleeping.
One other thing about the radio: this may sound like snake oil, but it is my understanding that the radio's reception can be stronger when closer to the ground based on how the radio waves travel. (It may have been a placebo, but I'm certain I have seen benefit from this on occasion).
I would also make sure that things like NFC, ambient display, screen rotation, adaptive brightness, sync, notifications and vibration are turned off (Being deaf, I suppose that no vibration may not be possible). I would also uninstall (or disable) any and all apps that are not absolutely necessary for the trip. I would also uninstall the Facebook app, if you are using it. If you prefer an app experience for it, I would recommend the Metal app in it's place. No matter what rom you install, you should go for optimizing the power usage.
As for the camera, I would stay away from the AHDR modes and stick to single frame (huge battery saving there!)
I would set a completely black lock screen and home screen wallpaper, too.
I would also suggest an automation app for managing your power usage. Most allow you to have predefined groups of settings that you can assign home screen shortcuts or a quick settings tile. I recommend Automate by Llama Labs.
Good luck! And I hope you have a fantastic trip!
So far that I know of, is that the CPU and GPU speed and governors affect how much the battery is used (#2 heavy power consumer behind the active-matrix organic LED screen with light background) - the faster they run, the more power they require to do certain tasks. I have since set my Nexus 6 phone's processor at 200 - 300 MHz to 1 GHz across entire quad cores (with AutoSMP hotplug and ondemand governors) and GPU locked to 300 MHz maximum, and that configuration have been saving me a lot of power (and quite noticeable with the new battery I installed last week). The ROM I am using is crDroid (Android 7.1.1 Nougat), if you're wondering.
As for GPS, it depends. It may just sip or hog the power. Vibration? It depends on vibration strength (which can be adjusted with Kernel Adiutor Mod app), the stronger it is, the more current it require. Long story short, experimentation is necessary. I also recommend to use black theme under Substratum, it will also ease current consumption by the screen, which I have been doing also (Swift Black Substratum theme pack is what I'm using, perfect amount of blackness to save a good amount of power, and can be found in Google Play Store).
I second cameraddict's suggestion of a power pack. I have the 3000mah version of this, and it works very well.
https://www.amazon.com/PowerCore-Po...&qid=1490282378&sr=8-4&keywords=anker+battery
There are others with higher capacity, but this one would more than double your N6's capacity, and it's the size of a small cigar.

Thanks for all of the ideas. I already have a 10,000mah external battery that I will be using..Unfortunately solar panel are not very feasible on the trail, there is a reason why it is sometimes called a green tunnel.
I'll be removing virtually everything unneccesary from the phone. I do use Facebook a lot but I'm planning on using titanium backup to freeze the app (plus other apps) when I'm not using it so it should not be a problem there.
Good idea about limiting to 3g when I'm on the trail. There, I only need minimal data for emergency messaging and basic GPS sharing.
I do have a pebble smartwatch and I'm thinking that maybe using it would offload the battery usage from the phone to my watch allowing me to still have some notification and other details on the watchface.

Yeah, that's why I'm asking about it at this point. I feels that 2 months are long enough for me to experiment with this. I'm hoping to do the trick with governers so I'll be reviewing your comment after work today.

Yeah, I have a 10,000 mAh battery, heh.
I'd go back to Marshamallow and not Nougat for battery savings. Also "Pixel Off" app to reduce brightness and turns off 1/2 pixels to save battery. You can also use Black and White mode in Developer Option to save battery. Kernel Audiutor can underclock to 1190 Mhz top and 300 Mhz bottom with "conservative" governor and "powersaving" mode.

I disagree, because I haven't seen a difference between Marshmallow and Nougat regarding battery saving (even though stock Nougat ROM blows - all the reason to install custom LineageOS derivative ROM instead) - I know because I checked with new battery installed and I am still at 56% battery remaining ever since 5 days after charging to 100%, on the Nougat ROM with aggressive economy CPU settings I tailored on my phone, however, as for 1/2 "Pixel off" and black - white video option to save a bit juice, I agree even though it will make the UI quite ugly.

I had another thought this morning. ( I realize that all my suggestions are minor, but lots of minor adds up.) I would also turn off all animations in Developer options.
I also wanted to agree about the monochrome color option in Developer options. And the dark theme, in general.
As for kernel settings, on other devices I've had, I had quite a bit of success with UV. If memory serves, once I had finished a weeks worth of experimenting, I gained about 10% from UV. And using the ondemand governor, with lots of tweaking, I was able to increase battery life without too big of a hit on usability. I found that powersave always created a very unpleasant experience.
edit:
One more thing, from my experimenting, you can also gain several % by changing how you interact with the device. Your governor will spike the CPU every time you touch the screen. One major difference you can make today is changing that behavior. When reading, scroll from the bottom all the way to the top of the screen and don't touch it again until you need to scroll all the way from the bottom. This isn't as hard or as silly as it sounds. Watch how you use your device, Many people touch the screen a lot
Despite every effort and tweak you can think of, you'll achieve only minimal battery life extension. Your best bet is to use the few tweaks that you feel are acceptable and rely on your 10000mah battery - nothing else will have anything like that effect.

Respectfully, I disagree. Each .5%-2% gain adds up. 10 tweaks at an average of .75% gain is 7.5% Add one major tweak that gives an average of 8% and you now have a 15.5% gain. My battery, right now, on official 7.0 (with no tweaks) averages 40 hours on battery with 6-8 hours of SOT. I have many other metrics for this... So 40 hours x 15.5% = total battery life of 46+ hours. Those 6 hours are not minimal effect. Especially when there is no outlet nearby for days.
It is possible with the right mix of OS tweaks, app settings and kernel tweaks to see an average gain in the 30-50% neighborhood.
This, by the way, comes from years of tweaking and experimenting on many devices. Going back to 2003 or so. You can check out my old posts on optimizing my old Galaxy S2, I shared a lot about that device.
No need for "respectfully" I'm sure it's really just a preference. A lot of tweaks may well add up to a respectable extension, but they will never triple it as a 10000mah battery will. I'd rather carry the extra few ounces and be sure that I have a reserve. Not arguing, just stating my preference.

Gotchya. I just mention all the tweaks AND the battery for his use case. As an initial full charge plus three extra charges(with the 10,000mah) without tweaks (conservatively) would net him a total of about 8 days of use. But with 20% savings from tweaks, that goes up to nearly 10 days. Quite a useful increase.
ps... I wrote: "respectfully" 'cause you know how forums can be. Sometimes I think it's best to be proactive and let the person your responding to know that you're not arguing. Cheers!
Morning all.
Something that has been slightly bothering me since I got this phone....it has a massive battery, it can be heavily customised with roms, xposed modules, magisk modules and all manner of tweaks. Probably one of the most open and dev-friendly devices I've ever had.
Yet, no matter what I do the only way I have ever been able to get more than 2 days out of a battery is to literally not use the phone.
I have had devices in the past such as Xperia Z3 Compact, S7 Active and others with smaller battery that were easily able to push 3 days with regular use. Hell, the Z3C was able to get up to 5 days with a little bit of trickery turning off radios when not in use etc.
Is the extra diagonal inch of screen realestate really enough to destroy the battery longevity? Typically with normal usage I am seeing 2 days with about 4.5 hours of screen-on time.
I've experimented with just about everything to push this out including no official facebook apps, decreased resolution, medium power-saving mode, kernel tweaks (currently using TGP rom and kernel), auto-sync turned off. Going beyond this I feel like you may as well just use a push-button device.
Any devs care to comment? What is the main factor that eats the battery on the Note 9? Is the exynos processor just not that power-efficient? Am I missing some hidden gem?
I guess the next step would be to transition to an AOSP based rom where the customisation is not constrained by baked-in samsung features but again, this is giving up a lot including proper s-pen functionality.
I recently kitted out an LG V30+ for my wife and it is just insane to me that a phone which only has a 3300mah battery can get the same life as the Note9 or better.
Is there some strategy I have missed or is this really the best we can hope for? Seems like an extremely inefficient use of 4000mah to me.

This is what you get when you use a high performance chip.
If it was like cars.. just because the gas tank is big (battery) doesn't mean that the engine won't consume the fuel faster than a more Efficient engine (cpu) with less power.
Other phones might be able to last 3 days, but they also dont have the performance capabilities. Turn on extreme power saving and see how long the phone lasts ...
I'm using stock unbranded ROM. I also adp uninstalled all the Facebook system apps (devil-ware). With Pie + OneUI + Night mode + Dark UI apps, it's the first time I love stock. I bet your non-stock ROM + TGP is the culprit.
I charge nightly on a wireless charge pad; easy on the battery. In Device Care, I run the default "Optimized" setting. I use it moderately for the first 12 hours of my working day (meetings phone calls), and I often have 85-90% charge left at that point. I then use the phone HEAVILY for the next 4 hours (watching video, reading, etc.), and at that point I am never below 50% (often 60-70) when I put it back on the charge pad, go to sleep, and start the whole thing over again. I have the US version (Snapdragon), darkmode and auto brightness is always on, and I use Automate to toggle my wifi off when not home and back on when home. Other than that, I have gps, bluetooth, and phone data always on. Bluetooth pairs with my watch and car, and gps auto-toggles by the kernel whenever I load maps or whenever my Life360 app updates my location (every few minutes).
That's all fairly normal use with a bit of power-savings thought into it. If you cannot get similar performance without your screen brightness jacked way up and wifi always on (that eats battery as you move around), then maybe you have a power-hungry app. Check your Device Care section of Settings, and start watching your "Usage by apps".
Also, it's better to slow-charge than fast-charge (wears it out more quickly). And you are better off charging nightly than waiting two days until it's very low.

A lot of people don't realize the huge difference that your cellular connection strength makes a difference on your battery.
Try working in a all brick/stone bank building, where 250kb/s is a good 4g download speed... Then see what your battery looks like after a few hours.

YEP!
And same goes for wifi.....
wifi and cell radios can really eat up battery if they are trying to maintain a connection in areas where wifi/phone signal is weak. And app like Tasker or Automate can toggle these on and off, depending on your location, and really save battery.
Well, that probably explains a few things. I moved in to a SOLID brick building recently with double glazing everywhere and multiple solid brick internal walls. First time I've ever battled for cell and wifi signal...that does explain a lot. I guess 2 days is still pretty good. Might end up with one of those 10,000mah Chinafones eventually ;p
I just switched from having iPhones all my life to the Samsung s21 ultra thinking it was the best possible android phone to get but it’s literally uselsss. It goes from a full charge to almost dead after playing a game in about 2-3 hours. In comparison my iPhone 11 which I hadn’t charged in about a day than played the same game for about 6+ hours while having YouTube playing in the background still has enough battery to go on for hours. It literally goes from 100% to 95% just unplugging and looking at notifications… idk it seems I’ve made a huge mistake… I watched many reviews prior to buying it and they all said the s21 got hours of use before a charge.
my s21 spends more time charging than any actual use and I’m left with having to pull out my iPhone to play games and watch YouTube. Hell it’s charging right now and I’m writing this using my iphone…
is something wrong with s21 ultra or is this normal ?? Should I try to exchange it ?? I just got it like 5 days ago.
I charge mine once a day (at night while I sleep). And average 5-6 hours of SOT... Great battery life IMO.
You're burning up your battery.
2-3 hrs of high intensity gaming is a lot to ask from such a compact device. A least give a break every 15 minutes. Even watching vids I give my 10+ a break every 20-40 minutes even though it's using only 2-4% more power than when browsing the web.
The big question is how much battery is it using when idling and doing light tasks SOT?
Roughly...
Should be around 6%@hr
Browsing Brave 7-9%
Vids 9-11%
Screen off AOD always on, >1%@hr
Screen off AOD tap on >.5%
This is what a optimized 10+ is getting. Yours won't be the same but if there's a huge 10% SOT difference it's because there are apks sucking it dry. The AOD night rates should be very similar.
In fact the S21U with a 5000 vs the 10+'s 4300 mAh battery should do better. The S21U's memory is about 20% more efficient and the CPU should use less at idle. The wild card is Android 11 which I'm not found of, vs Pie with no scope storage. That said I think you should still be seeing similar run times.
What's eating the power? With Android you have options, many of them unlike plain Jane Apple*.
Is your screen brightness greater than 50%?
The display gets very bright and eats a lot more current as you go past 40%. It also wears out the AMOLED pixels a lot faster past 50% and maybe your retinas too.
Do not use in direct sunlight. Not only bad for the display but the sun's IR energy can overheat the little greenhouse phone rapidly.
AMOLED displays eat almost no current when black. Bright wallpapers do. Big bright icons do.
After the display consideration look for apks that are using too much and correct it.
Try disabling all power management for now except the display/power mode. Address each problem app separately and their dependencies.
You can use a Package Disabler to troubleshoot and kill bloatware and problem apps.

Disable Google Firebase, and all carrier, Samsung and Google feedback. Disable cloud apps if not needed. Keep trashware like FB, WhatsApp, Instagram, Twitter, etc off the phone. Privacy, security risks as well as battery hogs.
Use Karma Firewall to block internet access to apks and services that don't need it. It's freeware that uses almost no battery.
Use the native launcher, it's fast, very stable and very customizable.
That's just the beginning...
*stock Samsung's are the most customizable phones on the planet. Use the Galaxy Store themes and icon packs, hundreds of free ones.
Use the Good Lock family of customization apks.
Use Sound Assistant.
You can spend months playing with them alone.
I've used Apples and I hate them. They run well but are so limited compared to Androids. That plain Jane bores me to tears. Android are what you put into them. Nothing in, nothing out.

I just switched from having iPhones all my life to the Samsung s21 ultra thinking it was the best possible android phone to get but it’s literally uselsss. It goes from a full charge to almost dead after playing a game in about 2-3 hours. In comparison my iPhone 11 which I hadn’t charged in about a day than played the same game for about 6+ hours while having YouTube playing in the background still has enough battery to go on for hours. It literally goes from 100% to 95% just unplugging and looking at notifications… idk it seems I’ve made a huge mistake… I watched many reviews prior to buying it and they all said the s21 got hours of use before a charge.
my s21 spends more time charging than any actual use and I’m left with having to pull out my iPhone to play games and watch YouTube. Hell it’s charging right now and I’m writing this using my iphone…
is something wrong with s21 ultra or is this normal ?? Should I try to exchange it ?? I just got it like 5 days ago.

If you're unhappy with it, best to exchange it and go for the iPhone 12 Max. Especially if you are already comfortable with the apple ecosystem. There's no point being frustrated with your most used device, especially after paying top dollar for it. Personally, I would switch to an iPhone in a heartbeat if I thought they offered value for money (according to my standards) and if iOS allowed for a level of customisation I've come to love with Android. Biggest reason I can't do that is that I don't like Apple's way of doing things as far as software is concerned.
As far as poor SOT is concerned - 2-3 hours is indeed quite less, even with a game. In my experience, the S21U has pretty decent battery life (albeit not as great as my brother's iPhone 12 Pro Max), and it's in line (if not better) with other phones running the SD888 (very comparable to the E2100), but I haven't tested it with games.
Just curious, what made you switch over from a lifetime of iphones to the S21U? It'd be interesting to know an iOS users perspective.

You're burning up your battery.
2-3 hrs of high intensity gaming is a lot to ask from such a compact device. A least give a break every 15 minutes. Even watching vids I give my 10+ a break every 20-40 minutes even though it's using only 2-4% more power than when browsing the web.

Even the newer iPhones use an OLED screen. They too run on Li batteries. If the usage is similar on both phones, 2-3 hours should'nt be a lot to ask from either device, right? Clearly restricting or modifying the user's behavious to cater to a device's personality shouldn't be the solution.
I guess each of us have different priorities and expectations. Your preference seems to be to disable everything that make Android phones so great - dim the 1500 nit screen and don't use in outdoors? Stop playing an engaging game every 15 mins? I'm sure it works in your use-case, but not everyone spends $1000+ for a crippled phone.
Then there's the fact that you have an entirely differnet device with a two generation old OS and completely different hardware!
The OP asked if he should exchange his device, if the S21U wasn't living up to his expectations, given his background of lifelong iPhone usage. The discussion wasn't about how to change his phone usage habits and teach him how a phone should be "properly" used.
There's a whole gamut of metrics to look at here: 1) iPhone screen resolutions are nowhere close to S21U's, 2) iPhone 11 doesn't come in 5G but S21U does, 3) iOS games are far better optimized for the OS than Android's, 4) Screen brightness, 5) background activities.
It's easy to pass a judgement before considering all the factors. I'm justifying that the S21U is better than iPhone or vice versa but you need to consider a lot of factors before closing an argument...Just my 2 cents

I agree with everything you just said.
Each person has to decide what is more important for him/her and choose accordingly.
No single phone is 'best'.
We get the device we like and need, and choose which compromises we're willing to live with.
In my example, I can't stand iOS, so I choose to live with Android. And among all phones out there, the S21U is my device of choice, with all its good and it's bad. I wouldn't exchange it for any phone out right now. But that may not be the case with everyone. For the OP, if long hours of gaming is a requirement, then the Apple SOC and optimised games push the dial towards iPhone.
If your battery is draining that quickly, there's a good chance it is defective. Before jumping to this conclusion, I would reset the device, keep it clean for like a day to see if the drain is still present. It would help to disable things like GPS (amongst other things) to see how much charge you lose over a few hours. In my experience, not all batteries come out the assembly line at 100% health - the same way that some products have defects while others don't.
If you have the option, contact Samsung, notify them of your experience. I have seen reports of people getting excellent battery performance on this phone. I have used Samsung devices in the past where battery life was really good. I wouldn't be so quick to write them (or Android for that matter) off.
Hope this helps.
I don't game, but here is about an average day for me. I could easily get another hour of SOT out of this.

The big question is how much battery is it using when idling and doing light tasks SOT?
Roughly...
Should be around 6%@hr
Browsing Brave 7-9%
Vids 9-11%
Screen off AOD always on, >1%@hr
Screen off AOD tap on >.5%
This is what a optimized 10+ is getting. Yours won't be the same but if there's a huge 10% SOT difference it's because there are apks sucking it dry. The AOD night rates should be very similar.
In fact the S21U with a 5000 vs the 10+'s 4300 mAh battery should do better. The S21U's memory is about 20% more efficient and the CPU should use less at idle. The wild card is Android 11 which I'm not found of, vs Pie with no scope storage. That said I think you should still be seeing similar run times.
What's eating the power? With Android you have options, many of them unlike plain Jane Apple*.
Is your screen brightness greater than 50%?
The display gets very bright and eats a lot more current as you go past 40%. It also wears out the AMOLED pixels a lot faster past 50% and maybe your retinas too.
Do not use in direct sunlight. Not only bad for the display but the sun's IR energy can overheat the little greenhouse phone rapidly.

Solid, useful reply all around! Social media apps and google/samsung telemetry hurt your battery and privacy. After removing ones you don't need, you can use Blokada or another firewall to block trackers and ads from what remains. Tech tends to be better when kept simple.
My S10e gets around 6h SOT with most apps disabled through ADB, zero google apps except for play services, and F-Droid + open source apps for most things. I wish I could run a degoogled ROM with MicroG, but this setup is 80% of the way and Samsung's customization without root is solid.

Now that you're not roasting your battery continue pick away at the serial offenders.
Try to get the SOT in the 7-11%@hr range.
Remember to clear system logs and clear the system cache.
Global ad blocking?
Easiest way...
I get over 19 hours on a full charge and play lots of games. Go to Settings > Battery and Device Care > Battery the touch the graph. That will show you which apps are using the most battery. Some games use a lot of battery up. And if you have Tiktok or Snapchat on your phone then those are known to cause battery drain.
Return the phone, 2 - 3 hours SOT is nowhere close to normal, even if you haven't optimized power consumption.
Hi !
I bought the pixel 5 for 10 months now. I love it but I wanted to know if other owners of this pixel 5 had the same concerns.
Whatever I do, basic uses like Twitter, Gmail, chrome... Behind at the top next to the photo module, The phone is always hot. I wonder if this is normal, and if you also have your pixel 5 heating up there.
Also I don't know if it's due to the fact that it often heats up, but I've always heard wonders about the battery of the pixel 5, But I must say that this is not my case, I had changed from my pixel 4 which I loved because the battery was really bad, but there on this pixel 5 the battery is better but not by much. I can only get 3-5 hours of screen time on a 100% charge. While I had seen a lot of 6-7 hours. So how much screen time can you do with your Pixel 5 on a 100% charge?
Thank you.
While I don’t own the phone i must say that newer phones heat up quicker in general. Most YouTube reviewers are just bias or dishonest, it’s all about your own experience with the phone. If your phone heats up it could probably be because your tackling the processor to much or overloading the available little ram the phone has, which causes the phone to heat up, because the phone is trying to keep up with your tasks. Try limiting processes, often restart the phone, and keep it in a cool environment (which is a difficult thing to do specifically with the hot weather these days), yeah that. I don’t know about the screen on time, but you shouldn’t believe reviewers to much.
I can easily go all day on a full charge with some pretty moderate use, including constant music streaming. I don't have any heat issues.
8GB RAM is not "little"; if you're running out of memory on a Pixel 5, you probably need to reevaluate your application load. The only app I have constantly running is NordVPN.
Your right, I thought that the Pixel 5 had 4GB Ram, because I forgot that it had 8GB
To further improve battery, you can restrict apps so they don't drain battery while the screen is off. Settings > Battery > Battery usage, select the apps you want to restrict while in the background, then select Restricted.
