OK, I know battery life is always an issue with PDA phones. I'm never far from a charger. I'm fine as long as I'm just checking e-mail (4 accounts, once an hour) and a little light web surfing with Opera Mini.
The problem arises when I use my phone as...well...a phone.
My Tilt loses battery power at an alarming rate when I'm talking on the phone. A 20 minute conversation will easily cost me 40% of my battery.
I'm usually in a non-3G area, so I'm on Edge. I normally have a good, strong 4-bar signal. Even when I'm in a 3G area, I use a different comm manager to turn off 3G to conserve power. I use KaiserTweak and select all the "Advised" settings in the power-related sections.
I've tried several different radios, but haven't noticed an improvement.
Does anyone have any ideas or recommendations on improving the efficiency of my Tilt in phone mode?
I have the same problem.
I have 3 batteries. 2 Samsungs and 1 Dynapak. Each battery lasts about 3 hours in standby. The phone is always warm as well. I have a utility that shows the phone is running around 380mAh current. That's seems pretty high.
I think theres something seriously wrong with certain batches of these phones.
these phones r seriously poor for battery life.. i love the htc but they slowly being overttaken by other phones.. shame!
maybe depends on the battery and ROM/radio because my Kaiser lasts 1 gay of VERY heavy usage+calling, and in stand by can lasts 6 days at least.

Really??
So, what battery are you using? Which ROM? Which radio?

mine too or maybe more. Normally I charge every 2 days.
Seriously though, hasn't this topic been beat to death with a stylus?
Ask youself this, how is your battery and what all is running on the phone?
If the battery is a year old then just accept that it's shelf life is over with. If your phone is always warm that would general mean that one of the radios is running, Wifi , data, gps? If any of those are running all of the time or when you are not using it, then your draining the battery.
I have a friend that beat himself up trying to figure out why his battery would drain so fast, he reflashed the phone 3 times a day etc etc etc. He just could not accept that it was a crappy battery. I got another (used battery) and it worked fine.

Me too used to get about 2 days with a 2700 that is being registered correctly, i now tell everyone to not phone me "well they don't listen just like no one does" so i block all incoming calls with MagiCall, to what point do i have a phone now? To flash & twaek and text
"Am kinda joking but my stylus is now half the size due to this topic"
Buy a new battery.
I don't dig long phone calls unless there is something going on. Too many people just want to hang out on the phone and say nothing.

"The loss of battery was due to phonecall and radio i'm not moaning either i expect the battery life to not be perfect on any WM phone"
Well yeah radio version help too.

This isn't my first foray into these HTC devices. I've been using them for nearly 2 years now, and I know the battery life on these devices isn't what it is on something like my old RAZR. I'm just fine with that; since the Tilt does so much more, I don't expect the charge to last a week like my RAZR did. But this drain while using the phone is driving me nuts.
FYI, I know to keep WiFi and GPS off, and to use KaiserTweak to shut down data connections when they're not being used. If I don't use the phone or surf, the battery will easily last me 2 days, and that's with checking 4 e-mail accounts every hour, and with SBSH PocketWeather getting updates every 2 hours. But talk on the phone, and it's a different story. I talked to my wife for about 30 minutes last night and went from 80% to 20% battery level.
The battery is only about 7-8 months old. Still, I ordered a new 1600ma battery last week, and it should be here in a day or two. I'm hoping that solves the problem.
It's possible that the battery you have now is under warranty. (if you bought the phone new)
good luck.

Unfortunately, it was a refurb, and the warranty expired a long time ago. The new battery wasn't exactly a budget killer.
Well my battery seems to be working now.
Phone is no longer hot all the time, and my utility says I'm using between 1 and 64 mA. That's much better than the 350+ mA it was sucking before.
I didn't do a damn thing different either. Didn't change any settings for the radios, didn't reflash, etc..
Some people think that the GPS get's stuck in the "on" position and there's no way to turn it off, short of opening and closing GPS Aware programs repeatedly until your current usage drops in the sub 100 mA range.
Always discharge your battery fully as possible at least 1 a week to ensure your battery last longer, lots of charges above the threshold will diminish your batteries life and capacity. The Kaiser is a powerful device and it is obvious to anyone that this requires power to run it, so the battery wont last for days. :-(

HUH???????
These are Lithium batteries, we aren't in the 90's anymore buddy.. My phone lasts for at least 2 days and sometimes 3 (the phone is over a year old too)..
Welcome to the year 2009
"1. Battery Memory - When I first got my new cellphone, my friend recommended to fully drain the battery before recharging it. His reasoning was connected to the idea of battery memory. Allowing the battery to fully discharge then recharging to max, supposedly gives you the complete battery capacity. Otherwise, if you simply charged from the half way point to max battery capacity, the battery would treat the half way point as the empty point, thus cutting your battery capacity in half.
Problem is battery memory doesn’t apply to Lithium batteries, this advice was meant for Nickel based batteries. Fully discharging your Lithium battery frequently can actually be quite harmful to your battery’s health, possibly rendering it completely unusable if energy levels go too low.
The good news is today’s lithium batteries have a safety circuit in place to insure the battery doesn’t reach the point of no return. The safety circuit isn’t fool proof of course, if you leave your battery completely drained for a few days, even the circuit’s protective measures won’t save it.
"
INFACT it's recommended to leave a little bit of a charge before charging or storing.
l o l
Be that as it may, when you get a new battery you still have to use it for a few weeks before the phone reports battery levels accurately. The phone may still shut down when WM thinks it's almost empty, regardless if it's actually empty or not. Just try it, battery life improves over the first few weeks of usage, and your battery level readings will get more stable (instead of dropping to 50% in 10 minutes and then proceeding to stay there for 6 hours).
BTW my kaiser lasts about 3 days as well, with fairly heavy usage.
No fair, I want a bazillion stars next to my name too.
I Think this guy has had the phone and battery for a little while, so the few weeks thing might not be an option. (well at least the battery he was posting about)

As refered to your reply, i didnt mean discharge fully completely i meant the cut off point would stop you anyhow, i meant to bring it to about 10%, i found that using the battery until it reaches 10-12% far by decreases battery drain when it is fully charged again, this is only 1 in a while though not frequently. I understand lithuim-ion doesnt have a memory effect problem, but there is such thing as variable current influencing different cells which can either benefit or make it worst, there is a lot of debate as to whether this improves it or not.
Great tip, keep it cool and away from your pocket pants because heat kills it.
Dude thats no fun to keep it out of your pocket,
Hi,
I know there are already threads related to Heating but wanted to see if theres a trend with all water proof phones.
I owned an Xperia Z for 1 year, and by the end of 12th month, the phone used to heat up lot and battery life wouldn't last even till 5 PM evening.
Where as initially it used to last a full day with same usage.
Then, I bought Z1 Compact, initially battery life was fantastic! within 8 months of using, today it too dosent last till 6-7 PM in evening.
Note: Auto Sync off.. and uninstalled all unnecessary apps.
My question is - Companies like Sony sell phones with great publicity promoting features like 'Waterproofing" "great battery", but is any of these companies following up with customers about whats happening after 6 months of usage?
Is water proofing affecting the thermal management and is it the reason behind increased heat and battery drain?
Are they still providing with good battery life? how much they heat up?
Because of that what impact is happening to the shelf life of the phone? Is the processor getting damaged?
Changing Non-removable batteries is a pain and expensive, people don't have time for that.
These phones become barely usable within 12 months...

Well most of these question can only be answered with thorough testing and comparison of lets say "affected" phones , phones without the water seals etc... while keeping the components and architecture the same.
Batteries are disposable products so why should companies follow up on this? Except for the cases where its really a hardware problem, like when your phone catches fire or something they wont care about this kind of degradation.
Generally you can say the more power the more heat development. Though the degree of this again is entirely dependent on the components physical architeture, material and the applied cooling solutions. So every smartphone will be different as regards heat development.
This phone is still too young to speak about the degradation of battery capacity. But modern batteries tend to do a fine job. Heat again reduces battery capacity and component life span so if u tend to walk around with your smartphone always recording in 4k it will live shorter. But that is kind of obvious.
Processor power does not really degrade. There is a point when it will die due to wear of the material but a processor either works or it doesnt. Hence a damaged processor would result in a non functional phone. Also the processor, if done the right way, will outlive other components in your phone so i would not worry about it too much.
What can be damaged as regards processor is the cooling. If it is not cooled down properly it will overheat, shut down and eventually be rendered damaged and unusable.
The two items that when looking at computers generally wear out are the harddrive (SSD or HDD) and the battery (as regards laptops). SSDs tend to have a huge amount of lifespan nowadays so battery is and will stay the weak point.Thats why more and more development is put into power saving features rather than pure power. Just look at the development of Intel. Processor power has not gone up much in the last 6 years, but power saving has. A smart move bcs more and more ppl buy portable devices instead of stationary workstations.
So yes , after two years of constant usage you may be down to 60% capacity of the battery.
Usage of battery is also said to be important, but here is where i tend to say just use it how you want otherwise it gets too complicated .
If you want to use your phone longer than that, without having to live with more frequent charging, you will have to buy one with a replaceable battery, get an additional battery pack like the mugen power or exchange the battery yourself. There is just no other way.
The trend of no user replacable batteries is a bad one. Yet profitable for the companies. You can see the same in laptops, only some of the top tier models like expensive lenovos tend to have replaceable batteries so they can last longer. Phones and Laptops are getting thinner and thinner (eg ultrabooks) which is used as an excuse that batteries have to be integrated into the case, leaving the (normal) user with no access to it. This is all a lie and just pure money making.
A solution for longer longetivity can also be that you cap the performance of your device. So reduce the maximum frequency of your processor, undervolt it and stuff like that. It will decrease heat development and battery usage but of course also decrease performance. But then you dont need the Z3 compact, which purpose is exactly that it is a very capable phone with a small footprint
at last here:
a generally good review site is this one http://www.notebookcheck.net/Sony-Xperia-Z3-Compact-Smartphone-Review.127925.0.html
if you scroll down they always test heat development of the devices. So you may get an idea of longetivity, if lets say heat development is unusually high.
Heat is a weak point of Li batteries for sure (it's why laptop makers, for example, offer much shorter warranties on batteries than the rest of the machine) but the heat doesn't have to be generated by the device. Leave your phone in a hot car a few times, or in the sun regularly, and the battery will take a hit right away. Even the way you charge a battery will impact its life over the long term (they hate being completely drained then recharged to 100% all the time, for example). There are so many variables that determine battery performance over the long term that it's hard to pin it to the device itself. From what I can tell the Z3c is no better or worse than every other phone I've ever had regarding heat generation.
I've always taken care to protect my phones from excessive external heat and have tried to charge them the optimal way and I generally don't notice a significant drop in battery life for 18 months or 2 years (which is when I upgrade anyway). The last phone I had with a replaceable battery (Nexus One) I swore I'd get a second battery after a year for optimal performance but I never did because I never needed to. It's also why I will never buy a used phone that's over 18 months old because the battery is likely to be well off its peak.
The Note 8 promised long battery service life, that is, high maintenance of original charge. Samsung promised that after a year, the battery would still retain 95% of its original capacity. Using Accubattery, my Note 8 has achieved this. This is vastly superior to what I experienced with the battery on my Galaxy S7.
I don't know much about batteries, but from owning Thinkpad laptops, I know you can get long service life from a lithium battery by deliberately not allowing it to charge to 100% of rated capacity (this is a setting in the Thinkpad battery firmware, accessible from Windows or Linux). If this is the same way that Samsung did this, it means the Note 8 battery has more capacity than it reports. (3300 mAh), achieving long service life by undercharging. This would mean that Samsung gets weaker reviews since out of the box it offers less runtime, but owners get the benefit of sustained runtime compared with previous phones. A pretty courageous move, if my speculation is true. The other possibility is that the Note 8/ Galaxy 8 has some very high spec battery technology which is significantly less exposed to typical capacity degradation.
So now, the Note 9 has a 4000 mAh battery but with almost no change in dimensions, which is curious. Is Samsung still claiming the long service life that it claimed in the Note 8/ Galaxy 8 generation?
I would like to know the answer to this as well.
The device is thicker and wider and 700mah isnt THAT much more physical size wise. But why wouldn't their claims on battery longevity still hold up?

I actually didn't find the same situation to be the case on my S8. I found that at new, the battery could pull close to 6h SOT, and after 500 cycles or so (checked with Phone INFO app), it was closer to 3.5-4h. Not that 4h is a bad figure, and it was still fairly respectable, but it is not 95% retained. Same for my mom's S8, at first was doing 6.5-7h, and now is pulling closer to 3h. I got my battery replaced under warranty at the 1 year mark, but my mom hasn't and it's starting to show.

It might be a bad software update. My Note 8 battery started to suffer until I upgraded to Oreo. Maybe some thing to do with refreshing the battery meter.

Have we seen any official documentation of retaining that 95% battery in Samsung product webpages or leaflets/warranty information??
It was all about official "Claims" for the S8/S8+/Note 8.
Samsung haven't made the same "claim" for the Note 9 yet. Probably will, without mentioning in any official documentation/product pages.

Yeah, it wpoould be best if they included 5.000mAh but 4.000 mAh is still acceptable.
I'd like to know how other's batteries are holding up. I've had my 9 for a month or two now and AccuBattery Pro is showing my battery health as 97% (3882mah) already. I'm not sure how reliable that app is for that stat, but dropping 3% already kind of has me irked a bit.
The only thing i have noticed is when my s7edge and s8+ got oreo my battery life on both those devices was no where near when i first got them. As for my note 9 the max SOT i have gotten so far is 8 hours and 12 min in QHD, i was sitting at 11% battery before i plugged it in.
I have the Mate 20 Pro and it absolutely smashes everything out there. It has outstanding battery life

There was a semi big debate about this on this forum. Accubattery Pro doesn't apparantly show the correct figure from the get go. I'm assuming you didn't use Accubattery from day one to show the before health stats to current? I say this because from day one mine showed 97% health or lower.
Aida64 app also shows the battery capacity at below 4000mAh from new. Hence why Accubattery doesn't show 100% health .
Either Samsung has not implemented 4000mAh batteries in many devices or they are designed in such a way as not to show their actual values in apps.

My Note 9 is 5 days old, and Accubattery says 94%. It's nonsense.
So basically AccuBattery on the 9 is only really good for the charge alarm it sounds like. That makes me feel a bit better. Either way I get great performance so I'm pretty happy with the phone. I normally get between 8 and 10 hours sot so it blows all my older phones except my Note 4 with 12000mah battery out of the water.

Those apps are just estimating. There is no hardware components for such accurate power usage observation in the phones to tell you exactly how much the battery degraded/hold in the first place. Don't trust them that much + battery life in long run is not affected only from the battery degradation, but also from updates and not least important - the applications themself that becomes heavier with every update = the CPU/GPU scales higher and that needs more power and thus shorten the battery life.
Simple example, my HTC M8 eat for breakfast every app back then when it was released. Messenger? NP! Facebook? Lol, 10% CPU usage. And so on. Nowdays it will still run all of those fluid and fine, but instead of 1500MHz 2 cores for example, will use 4 cores at 2000GHz. This affects power usage when it's all apps basically. So it's not just the battery degradation.
That should sum it up about the topic.
My note 9 is also around 94% battery since day one. But this was not the case with the Note 8. I was at around 103-105% battery capacity on the Note 8 for a long time.
It is an estimate and not perfectly accurate but Samsung does have the ability to measure battery wear.
On jailbroken iPhones you can get the exact wear percentage and now iOS has battery wear shown directly in battery settings.

Your first paragraph, same here. Hence why I mentioned either Samsung have changed something battery electronics wise or they are not giving us usable 4000mAh.

So I bought the new S21 Ultra on the pre order the day it was announced. I was one of the lucky ones to get early so I could leave a review.
Coming from a Note 10+ that I had for a year and a half, I was really excited for the S21 Ultra, but was really disappointed with the battery life. I've had the phone for 5 days now and since the very beginning I've not been able to use the phone for the whole day on a single charge. It's been giving me screen on times comparable to my Note 10+ (4/5 hours) which is a much older device, but I thought maybe this was the way all S21 ultra's were behaving, just not very good battery life.
BUT, yesterday all the youtubers started to publish they're videos comparing batteries with older S devices and Iphones and their S21s were doing amazing, giving them screen on times of up to 13 hours!
I contacted support but they said this would be normal as my phone was still learning user patterns... but I'm not sure if that would affect it as bad as it is at the moment.
Also, I installed accubattery which is not 100% reliable but compared it to my note 10+ and it seems that battery health is even lower that my Note (95%)! Which I've had for a year and a half!!!
What do you guys think? Should I send the phone back? I'm really concerned that I just spent all this money on a new phone for it to be so bad with battery.
Try disabling all power management.
In Developer options>standby apps all buckets should show as active otherwise power management is running.
Google Play Services, Backup Transport and Framework are known hogs.
Disable all the bloatware, turn off auto sync for gmail, turn off all feedback.
You'll need to sort it out and optimize it. Took me months to get my 10+ sorted out. Fortunately it's running on Pie so I had more diagnostic options.
Returning is a thought as 5G may have been poorly implemented and another source of power drain. I think everything after the 10+ 4G both hardware and OS are train wrecks... I see very little incentive to "upgrade".
Maybe post screenshots that aren't below 5 kilobytes. Lol. I'm guessing you have an Exynos variant?

So I bought the new S21 Ultra on the pre order the day it was announced. I was one of the lucky ones to get early so I could leave a review.
Coming from a Note 10+ that I had for a year and a half, I was really excited for the S21 Ultra, but was really disappointed with the battery life. I've had the phone for 5 days now and since the very beginning I've not been able to use the phone for the whole day on a single charge. It's been giving me screen on times comparable to my Note 10+ (4/5 hours) which is a much older device, but I thought maybe this was the way all S21 ultra's were behaving, just not very good battery life.
BUT, yesterday all the youtubers started to publish they're videos comparing batteries with older S devices and Iphones and their S21s were doing amazing, giving them screen on times of up to 13 hours!
I contacted support but they said this would be normal as my phone was still learning user patterns... but I'm not sure if that would affect it as bad as it is at the moment.
Also, I installed accubattery which is not 100% reliable but compared it to my note 10+ and it seems that battery health is even lower that my Note (95%)! Which I've had for a year and a half!!!
What do you guys think? Should I send the phone back? I'm really concerned that I just spent all this money on a new phone for it to be so bad with battery.

It's too early to judge the battery life, also accu battery app is not good at all, it's not accurate as your own phone's batterymeter.
Also, you need a week or so to make sure the phone get optimised according to your usage.
Does your phone have Exynos 2100 or Snapdragon 888?

Mine has the Exynos 2100. I was just going off from videos like Mrwhosetheboss. He got 8 hours of screen on time. And he probably tested it when he got the phone no? And I'm litteraly getting half of that... and not even pushing my phone to the limit like he did on his video. I mainly use social media apps and YouTube.
I suggest doing a factory reset before you think about sending the phone back. Also, initially, be careful about what aps you install - try going with a minimal number of aps so you can get an idea of how the battery does when there are no aps that might pull from the battery - after a few days, add all of the aps you have been using (while avoiding any that might be a battery drain) and try for a few more days to see if you are seeing improved battery life. Good luck - hope it all works out for you.

Reloads -never- find the root cause and many times even if the problem is "fixed" it eventually returns.
Exceptions; old loads, software induced bootloops, viruses, and major firmware updates.
Expect issues with the 5G devices from poor hardware implementation. No fix for this.
I am on the first charge, but the battery life is so far pathetic. Omg! And everyone on youtube praise it... Down to 85% in 2 and a half hours and 50 minutes of SOT. Shame...

How much with screen off is it sucking down?
If more than 1% @ hr with AOD on it's probably Google and cloud crap running in the background.
You can optimize it to improve performance.
It's easier to do this with Pie though; Q and 11 take away critical tools and use scoped storage which wastes cpu cycles.
Get Karma Firewall and a package disabler like this one;

Regardless of the model or OS version most carrier phones will need to be optimized for good battery life and optimum performance.
My 10+ was a hot running bandwidth hungry hog until I toned it down. Today it's hard to believe it's that same machine.
You are right, I agree with all you said. It is kinda sad though, as for instance, my ex Asus Zenfone 7 Pro had an absolutely mindblowing battery life, without any tweaks. I just used it. With all the hype around the S21 Ultra, I believed it again. The only Samsung I used with good battery life was S20 FE 5G.
Will give it a go with what you say though, thanks.

Well, i believe what you are saying about battery life, but what i have seen so far is promising, i mean when S21 Ultra with Exynos 2100 beats iphone 11 Pro Max and 12 Pro Max, i guess that's a good sign!! But for sure, we use our phones in different way than each others because maybe you use it with 4G/5G enabled almost all the time while these tests are just using Wifi and maybe without any SIM card which means the battery consumption will be minimum at this part.
I have S20 Ultra with Snapdragon 865, i get like an average of 6 hours SoT and if S21 Ultra Exynos gives me the same SoT, i'll be happy!!
SOT is not everything...we travel, we move, you cant accept a phone that gives you 12 hours of standby in total. This is bs and useless, you cant rely on such a phone.

My AT&T 10+ was not real bad (or good) the first few days. After enabling power management it went to hell.
Eventually I disabled all power management and one by one tracked down the hogs.
Because of dependencies simply disabling and/or turning off say Google Transport and Google Framework isn't enough, firewall blocking Google Play Services* then clearing data on all 3 periodically finally stopped this hog dead in its tracks. These will run in the background when the screen is off stealing power for nothing. Sometimes the Google apks are misreported as other Google apks presumably because of the interlinking dependencies.
Try using Galaxy Labs Battery Tracker.
Developer options>running apks/cache can also yield clues. With an unrooted phone there's some serious game playing to track this garbage down.
Anything app that's cloud or carrier is bad... lol.
Disable all feedback and syncing except for texting; manually sync gmail.
*needs to be unblocked occasionally for gmail to download and for Playstore (another apk you should disable/firewall block when not using).
Try disabling 5G if you are not using it, for some ppl SmartThings drain a lot of battery but you should see that app in log. Can't wait to get mine, also E2100 and coming from Note 8. Was rly looking to have a 2 day phone.

That's a thought that's worth a try.
From what I've read even disabling 5G doesn't completely stop it's parasitic battery drain.
Maybe the latest generation chipsets are better but early 5G was poorly implemented giving a marginal speed increase on most phones of 20% when available.
Is this on the snapdragon or exynos variant?

So, 15% drain in 2.5 hours with nearly an hour of SOT. 15% is about 1/7 as a fraction. Now, 7 * 50 / 60 = 5.83 hours of SOT and 2.5 * 7 = 17.5 hours total. My Note 10+ (S20 Ultra on order!) doesn't do any better and NEVER did. If I use my phone for 6 hours a day (of SOT) it's pretty much done for.
I think people are being way too picky these days - just complaining to complain. If you really want I'm sure you can tune your phone so it gets 3 days on the battery. It'll suck and not do much of anything but, sure, you can do it. I've got a smartwatch and the same thing applies. I can tune it so it works for two weeks on the battery or I can actually use the thing and get 2-3 days. I choose 2-3 days and have stuff I want to use. I'd rather my phone be reactive and tell me when I've got emails, etc than to get super long battery life and basically have an inert brick in my pocket. I have a cellphone so I can use it for stuff. If that makes the battery not last long, oh well. If it can get 5-7 hours of screen time while also lasting through the day, great.
My 10+ draws roughly 1%@hr* with AOD on.
SOT draw varies between 9-12%@hr
Roughly 10%@hr watching vids on Samsung internet with surfing on Brave being the highest usage.
I consider it fairly optimized at this point.
*4300 mAh battery with little degradation.
No 5G running on Pie so not scoped storage either.
Figures are from a charge range of between roughly 40-65% as I rarely charged beyond 70% or discharge deeper than 30%.
Actual usage be more if I had started at 100% because of the power density difference through the power range ie 1% at 20 is far less watts than 1% at 100%.
A/V=watts. Less voltage means less overall mAh per % plus the additional losses due to voltage stepup power conversionas you dip towards 30% The closer to 100%, the higher the voltage with more available mAhs per battery% as well as less stepup voltage power converter losses.
A phone's wattage and V+'are constant so as the battery voltage decreases it draws more current ie mAhs.

You are also right, but , when you used something that does both keeping you up to date, and having a brilliant battery life, then it becomes disappointing when you change it for one that doesnt.
Hi There,
I've had my Note 9 since December 2018 and it has treated me very well. Still does all that I need to do, as fast as I need to do it.
One small problem - the battery life is fully shot. Having to charge multiple times a day. I tried a while back to see if Samsung would do this for me, but they suggested that I wouldn't get much of an improvement in battery life due to software updates etc. I assumed this was sales bs but have found mates to have battery replacements to make a difference.
Therefore - is it worth doing a battery replacement on this device? I get about 5 hours I think at the moment. I would be interested in your experience. Just to add, I've smashed the bank panel pretty badly (everything still works) so probably would want to replace this as well (as they are a fiver on ebay - again purely cosmetic).
Thoughts?
I did it 1 month ago. It's now waiting for the 3rd battery, been for 1 week in the shop. All the new ones ware manufactured in winter 2018 and were weaker than the 2900 mAh left in mine after 3 years, so no.
Fair aha thank you !
By the way, just got the new replacement. It's much better at 3600 mAh after one charge, and I could get around 6 hours of Revanced yesterday with 25% still left.
Interesting - and you have had success with it?
I'm just sitting here googling this very subject. My battery is still pretty good in normal usage, but struggled to get through a full day in a recent hospital stay (when, admittedly, I was using the phone much more than normal). Torn between a battery replacement, S23 Ultra in a few months, or stick it out for another year and hold out for the S24 Ultra. Note 9 is still perfect in every sense (I have the 512Gb version), it's just the battery life is starting to weaken. If, as you say, the genuine replacements are manufactured in 2018, I might just go for the third option and hold out for the S24.
I use AccuBattery for a long time. It estimates my 3 years old Note 9 battery is 74%. I go to service center and change battery. Now it's 100% after a few full charge. I feel significant improvement in battery usage, maybe 1-1.5 hours more on-screen time with same softwares, same usage.
