Am I the only one asking, why didn't Samsung include a 1850 mAh battery (like they did in the Galaxy SII Skyrocet) for the G.Nexus?
I mean, unless ICS is optimized to use very little juice (which people are telling me it's not really), I don't understand the decision to go with a smaller battery.
Engadget's review of the Galaxy SII Skyrocket says the 1850 mAh gives it impressive battery life. "Its 1,850mAh juicepack may play a huge role in keeping the phone powered on for a healthy period of time..." http://www.engadget.com/2011/11/11/samsung-galaxy-s-ii-skyrocket-review/
I know it's too early to tell, but I'm a bit worried about the battery life for the GN.
You really think an extra 100 mah is creating awesome battery life?
I invented cyberspace. You're trespassing.

I don't know, but you make a good point. I'd love to see 2000+ mAh batteries offered.
AndroidandMe once wrote a decent op-ed about how battery technology needs to improve, that it can't solely rely on the software developer's end to make OSes drain less; this is only half of the solution. The other half needs to be batteries that can either last far longer, or charge far quicker.
It'd be exciting if battery technology was heading toward a "super quick charge" state, where one could plug it in for 10 minutes, and get a full charge.
I'm not seeing a lot of news on battery development, though. Or am I just missing the reports?

I think this is a good sign, though I'm skeptical. Don't get me wrong, I'm rooting for the GN to have awesome battery life. I'd love for some verification on the maxed out and full-LTE settings.
With no announcements about improved battery life on the HD SAMOLED, I don't expect it to have any significant improvements over the current screens. 5-6hrs is more realistic of "continuous" use. And some sites define "continuous" differently. Watching a movie probably won't use as much power as browsing websites on 4G networks.

My cousin is doing her graduate work at Texas on this battery technology situation. They have made huge leaps and bounds over what we all get to play with outside of the lab, but it is so expensive that it will never see a market. I mean cool (read: expensive) stuff like super-cooled nano-tubes (super-cooled ceramics have almost no electrical resistance), microbial-perpetuated energy (small amount of energy in, small amount of energy trickled out over an appreciable amount of time), and increasing the capacity for inductive charging. I always feel like she is holding out on what technology is around the corner, but she has shown me some of their technical papers and there is no super secret mind-boggling technology around the corner, just "promise." Last I talked with her she was doing something with wavelengths and duration of energy over time (inductive charging). It's interesting but unless we want a couple million dollar devices, it isn't feasible (yet).

Talking to her, this is much more likely. In fact she says they have rapid charge technology (like < half an hour for a Prius battery), but it is both very expensive and unable to be mass produced. Although I feel like someone has advertised this at one of the auto trade shows or something, fairly recently. She mentioned this in terms of an inductive rapid charger that will charge your car when you pull into your garage or in powered parking garages, but she said it was at least ten years out. This is coming though...

Does anyone know how much it is to produce a battery that has 2000+ mAh versus a battery that has 1700-1800 mAh?
Seriously tho, isnt battery life on all smartphones subpar, just saying.
Ive had bout every top smartphone dating back the SE-P800 and battery life comes up...every phone on xda has "battery life not good enough thread." Just plan on charging it everyday or take another battery with you and problem solved.

wow.. my Desire HD lasts around 10 hours which I consider pretty bad and its only got a 1230 mAh battery, but then again we barely just got 4G in some cities here and I don't plan on using it so I guess that I can get at least a couple of hours with the more battery friendly screen.
at least I hope so.

You're right to say most smartphones offer a day--more or less--of battery life, but some are better at it than others (e.g., look to the iPhone 4, not 4S), and it doesn't mean battery technology doesn't need to improve.
With how large screens are becoming, and with LTE/HSPA+ and just generally more data-usage, battery life needs to keep up as well.
Of course, there are alternative solutions in the mean time, but usually they are inconvenient. Charging it every night is a given to combat quick drainers, but sometimes when you're out for the whole day and night, it's worrisome to see your phone reach that danger area (15% or so), while knowing you still need it to make calls, use the GPS, etc. Also, carrying an extra battery can be a burdensome annoyance for some.
Also, despite all the features that are offered (ie. widgets, live wallpapers, live location tracking, 4G speeds, etc.), something feels amiss when you have to avoid using these, often touted, features in order to sustain battery longevity.
I understand what you're saying too. It is what it is. But it'd be great to see battery technology improve (and be affordable).

Maybe you should read the article.
*AND I QUOTE*
"By heavy usage, we’re talking about contsant 4G LTE data use, playing games, listening to music and so on" (copied and pasted from the article)
That pretty clearly explains what they mean by heavy usage. Sure, we're not getting exact figures of time spent doing each individual thing, but constant use of those things would kill *MY* phone in under 10 hours (Galaxy S II), so if the Galaxy Nexus can last just as long on LTE doing the same things? I'm down.
I never cared about battery life because I always carry extra power with me I've done it since the iphone 3G always, battery pack and an extension cable works for me, I won't change the battery on this because it would require removing case and disrupting the screen saver that I plan on putting on
case will be an AGF ballistics if it's compatible

About 10% more. And it'll be about 10% larger.
I'm not concerned with the battery life persay, as I think it will be pretty good comparatively. I am concerned with the battery life on LTE, as every LTE phone out there is simultaneously great speed and frustratingly battery killing with LTE on. Even on standby mode with lte enabled on my thunderbolt...drain, drain, drain. I can't wait for that to be improved, and I haven't heard anything indicating it will be any different for the GN on lte.

I did read the article, which is why I said continuous/constant usage for music playing vs playing games would have very different battery drainage.
Of course, if the claims are true, it would indeed be a marvelous improvement.

The second-gen integrated LTE radios should be a lot better in terms of lower juice consumption. Even more so when there doesn't need to be a second CDMA radio in the mix.
But the second-gen hardware won't appear in devices for about another year.

Bit of an oxymoronic statement
I am hoping the pictures of the i515 battery posted in Samsung's accessory store are correct. *The words say that it is a 1750mah,*but If the picture of the i515 battery is correct on Samsung's site. That is NOT a 1750mah. It is a 2100mah battery. The picture shows 7.77Wh at 3.7v which calculates out to be 2099.999999... Or a 2100mah. The battery of the gsm model shown in Hong Kong is 6.48Wh at 3.7v calculates to 1750mah. Maybe it is the extended battery on Samsung's site. It is definitely for a galaxy phone cause it has the NFC wording on the back, and it is not for the Galaxy Note cause it comes with a 2500mah battery. Maybe this is how the galaxy nexus is doing so well on battery life in the latest battery reports. Hope the Verizon i515 comes standard with a 2100mah.

I gather both Seidio (sp?) and HTC had extended life batteries for the original TP, and Seidio had one large enough to warrant a new back cover. Based on Pocketnow's full review, I'm betting the standard battery isn't going to satisfy me.
Does anyone remember how long until those batteries came out for the TP after it launched, or have a theory about how long until they exist for the TP2?
No idea about that, but I can tell you the battery life is ace so far. And I mean ace.
I got the phone Saturday morning, been playing with it loads (the phone), making or receiving two hours of calls, loads of texting, photos, a bit of GPS, some tinterwebbing, push email the lot. It's been off overnight, but with all that, it's now Monday lunchtime and I've two bars of battery left on the Power Management screen and one bar showing on the title bar.

I agree battery life is so much better than the blackstone I had. Still 65% charged and had it on a day and a half now using it a lot.
I was also reading the pocketnow review about poor battery life, I hope battery life will be increased because I HATE the poor performance of my Kaiser device!. Charging it EVERY DAY es horrible!
You cannot get the phone in the morning and think.... "if I use gps during 20 minutes, maybe I cannot go home without charging the battery this night.." isn't it?
Mines been great but then again i didn't have a problem with using my Tytn II. For the device it is with a huge screen and all the features it is brilliant but if your going to be running gps blue tooth wifi checking 7 e-mail accounts at ~30 secs and having all the web pages you can pushed to you then yes the battery life will be terrible.
My manager at work is one of the worse for this ... it has the features so i will use them is his argument... mine is it also provides an off button for them use that as well.
I think you'll be pleasantly surprised overall with the battery life but if your going to be using it heavily then expect it not to last you a week
I probably would have wanted an extended life battery even if no one thought that the battery was poorly suited to the device. That's just me. The fact that it is coming up short for some almost certainly means I'll be looking into it.
People have different usage patterns and tolerances, so I'm not surprised 1500mah is enough for some. When someone puts out a 2000mah battery, I'm still gonna be like "Really? Only 2000?"
Seidio ussually launches accessories fairly fast when a new device hit's the streets...so keep your eyes open. Do you have the TP2 yet?
Also, check Ebay for accessories like extended batteries...
Myself, I have never needed one.

I don't have it yet. And I won't really need the extended life battery from day 1--but as far as accessory purchases go, like pouches and cases, I'd like to know what battery I'm going to get and if it will increase the TP2's girth fairly early on.
Although I've purchased PDA batteries from ebay before, including from chinese companies selling their, I'm wary of doing so with the TP2. I'd rather buy the best this time around from a company with a reputation to protect. I aim to own my TP2 for LONG time so I won't take the kinds of chances I've taken with lessor hardware in the past.

I normally go straight to general, but I've bookmarked the accessories subforum now. Thanks
As many of the launch phones are fairly similar in terms of specs, I am wondering if battery life might actually be a larger factor in my decision to buy a WP7 device.
For example, my first instinct would be the HD7, however with the largest screen will it likely eat through the battery at a rate of knots, or is the lack of true multitasking and microsofts minimun specifications likely to help ensure the battery life exceeds many existing smart phones, such as my Nexus one (which usually only lasts a day for me).
I tend to take spec sheets with a pinch of salt, as they often don't match real world experiences, but would love to hear from any one that has had a chance to test a WP7 device themselves.
My rule of thumb is that the larger the screen, the more battery it uses since the display it's the primary drain.
However, since the HD7 is the thinnest launch phone, it could be a good candidate for an extended battery that wouldn't make it too bulky for everyday use.
The problem there, is a WP7 to me is desireable specifically because of the UI and general asthetics over my existing Android (which I feel is actually superior to WP7 in terms of functionality). Clamping a giant battery to the back would ruin that effect for me.
I'm struggling to find much comparitive information on each WP7 battery size. Any else able to find a list? I've seen a few websites that I would not normally trust indicate the HD7 only has a 1200mAh battery, which is one of the smallest of the WP7s. Surely that would be a bit of a weak chinc in the HD7s armour?
The hd7 has a smaller bathe then the Mozart, from what I see the omnia7 is the best as its soles screen and the biggest battery I have seen so far

Dell Venue pro is 3 hours or up to 7 hours talk time?
They have 2 different info from microsoft websites.
http://www.microsoft.com/windowsphone/en-us/buy/7/phones.aspx#detail=1568
The same for Samsung Focus. Because of its thin profile I am willing to believe 3 hrs of talk time over 7, which seems exaggerated.
Focus/Omnia7 are listed as 3hrs talk time? Sounds strange. I heard it had a 1500 mAh battery - coupled with the more efficient S-AMOLED screen it should have more...
HTC 7 Trophy - has a Removable and Rechargeable Lithium ion or Lithium-polymer battery, 1300 mAh.
HTC 7 Surround - has a Removable and Rechargeable Lithium ion or Lithium-polymer battery, 1230 mAh.
HTC 7 Mozart - has a Removable and Rechargeable Lithium ion or Lithium-polymer battery, 1300 mAh.
HTC HD7 has a - Removable and Rechargeable Lithium ion or Lithium-polymer battery, 1230 mAh. Small battery for such a large screen.
Samsung Omnia 7 / Samsung Focus Has a Li-ion, a 1500 mAh. (Only 8GB of storage)
Dell Venue Pro is listed as up to 7hrs talk time / 14 days standby. It's got a decent size battery and the AMOLED screen which likely helps cut down on the power consumption.
I'd wager a guess that the S-AMOLED and AMOLED phones will have the longest battery lives, so long as the OEMs don't gimp the battery inside.

Samsung's site says:
Up to 300 Hours Standby Time
Up to 6.5 Hours Talk Time
Just for reference, for the iPhone4 Apple claims:
Talk time:
Up to 7 hours on 3G
Up to 14 hours on 2G
Standby time: Up to 300 hours
The Samsungs, when using dark themes. 1500mah battery with AMOLED will last you the longest. LG with 1500mah when using light themes. Power draw of the rest of the electronics should be more or less the same, since the platforms are almost identical.
Was about to say something similar. AMOLED should be really good with WP7 as it's quite a dark OS. Those screens take a tiny amount of power to display black (and loads to display white). Combined with a 1500mAh battery and you'd expect the Samsung to do the best.
From what I can see the LG phones have the longest talk time by far (10hrs).
I also thought the AMOLED screens were supposed to be great on power consumption but Im not so sure that works in real life...the samsung phones that I can see are all rated for 3 hours which is really too little...

Omnia 7 battery life...

I was thinking the Omnia 7 was going to be the phone to get with its 4 inch Super Amoled screen and 1500 mAh battery, But 8GB memory is just to small.
Why no 16GB version Samsung???
Well, I have never had a problem with battery life, on my Vibrant I had a pretty decent run with some sporadic use. With my G2 I had an alright run, but it had an underclocked processor so most likely that helped with the battery life... I don't know, Android has "multi-tasking" and that can hog up the battery a lot. So maybe it might hold up alright on the HD7, regardless I always carry a USB cable in my car, and a car USB adapter, just in case.

You make a good point...2G vs 3G...on MS site they show the 3G phone times for Samsung it seems but I wonder where the 10 hours come from for the LG...2G or 3G...believe it or not 6 hours(370min) is not enough for me...I know that is best case and with other things running on a smartphone it will be more like 4-5 hours...
i like win 7
Samsung's phone will most likely last the longest as it has quite a good battery and the screen uses less power than other screens.
I still have about 10 days to try this phone out. I'm trying to get a phone that will last me a work day and a little beyond so i'm not so worried about my phone dying on me.
I do quite bit of emailing, GPS and Hotspot. And though I'm impressed with the GS3 Verizon (much better than my GNEX), I'm sad to say that this phone could have been better with perhaps 2500 mAh battery. Instead of trying to make the phone as thin as possible, keeping in line with Razr Maxx thickness, it could have done it. a whole day phone.. I'm not a apple fan but it's about damn time Android phone last longer. not really apples to apples but still.
I hope that within the next 10 days someone announces a slightly larger battery that' doesn't change the thickness too much, otherwise.. this phone goes back to verizon minus $35 restocking fee, and i go buy a large bulky, ugly extended battery for my GNEX.
ummm my battery is really good. I have been often getting > 24 hours per a charge.
The phone actually has very decent battery life, especially considering the size of the display. I think you should read into battery management a bit. Mine goes 2 days without charge, but I don't play with it all the time. First few days when it was always in my hands, it would last about 12-14 hours.
Go into the app manager and disable the bloatware that you don't use.
Why dont more people embrace the fact that these phones have removable batteries and are like 10$ with charger on ebay. Seriously its not an iphone you arent helpless. I have three extra batteries for this phone, still think it has amazing battery life compared to my old phone

I agree, this phone gets terrific battery life. I'm getting 5-6 hours of LTE screen on time. Try disabling some of the bloat apps and turn down your screen brightness. If you primarily use apps with white backgrounds, use the inverted colors widget. AMOLED screens consume no energy when displaying black, but consume 3x as much as a LCD when displaying white.

so you buy a $600 phone so you can swap batteries during the day? and carry that battery around? lol...
i'm not trying to be sarcastic here but that's just ridiculous.
again, i'm hoping due to the fact that this phone is release through all carriers, their will be some company out there that will make a perfect size extended battery. sort of like what samsung did with Gnex 1850 to 2100 with cover. about 10-20% increase would make this phone perfect.
if not, then i'l just return it. wait for the unlocked version of this verizon phone, so at least I have Roms/kernel that could improve batt life. just like what happened with GNEX.

might sound ridiculous to you, but i wanted the fastest phone i could get (i do A LOT on my phone) and this is the fastest phone on Verizon (unlimited LTE Data plan). IF the best battery life out of the box was top on my list i could have easily went with the Razr MAXX.
i bought the phone knowing i would be wanting more battery life. but i can upgrade the battery. you cant really upgrade the Razr MAXX CPU/RAM...
i agree with you, and hope for a "medium sized" extended battery comes out. i would think it would be the best of both worlds.
I kind of see what you are saying, but it's definitely not a big deal to carry around another battery. I used to fly a ton and had the HD2 coupled with 3 extra batteries, and it was no big deal. I love this phone, and I get at least a day and a half out of it without issue.
Try some of the battery management techniques mentioned above. Personally I think Sammy did quite a nice job of balancing size, power, and battery life.
Yeah are you seriously making fun of carrying around tiny batteries when you want to buy a $600 dollar phone and put an ugly huge extended battery on it? I had 9 batteries for my mytouch 4g. Never had to charge it. Left.
Batteries in my backpack and car etc.
Seriously take the plunge and give up caring about battery life and charging

Yes. If you want a nearly full featured computer in your pocket with a screen to match, and a blazing fast network, that is the price you pay. It lasts as long as my Droid X, with specs that are tenfold better. I just bought a pair of nfc enabled batteries and a charger for about $20. Not really cumbersome, or difficult to deal with.
I guess I could have gotten some slow, 3g phone for a few dollars less, and had the batteries last two hours longer...
i'm not trying to be sarcastic here but that's just ridiculous.

You pay to play. Either sacrifice performance/specs, size,or battery life, or wait 3 more years for some breakthrough in battery technology.

again, i'm hoping due to the fact that this phone is release through all carriers, their will be some company out there that will make a perfect size extended battery. sort of like what samsung did with Gnex 1850 to 2100 with cover. about 10-20% increase would make this phone perfect.
if not, then i'l just return it. wait for the unlocked version of this verizon phone, so at least I have Roms/kernel that could improve batt life. just like what happened with GNEX.

That comment only makes sense if there were plenty of smartphones out there that got more than 24 hours on a charge. Get real, that is not the case. Not trying to be rude, but I just read about a 4500 mAh battery that takes an extended cover an I'm sure there are other options out there that don't require a different cover. Did you search at all?

This guy said it all. I'm happy with my two batteries and have no problems changing them out.
Link to a 2300mAh battery.

I ordered one today for testing. Has anyone else tried these out? For $9/US ship, it seems too good to be true.
Also, here's a 1500mAh for $4/free shipping:

I will be running standardized use tests when they arrive. Will report back here

I bought the 4$ OEM off eBay and it was worse than my already dying battery. Then paid for a mugen 1800... not that much better

I've read mixed reviews on these bargain batteries. We'll see I guess.
There were three 3500s left when I posted this thread.. now there's 2. Who else bought one?
I plan on running stress tests from full charge. (screen on 100%, gps on, wifi, data, fm radio, and google music streaming)
The best battery I used was 2 evo4g 1900 mah batteries for 7$ on eBay. The battery lasted 2 days with decent use but unfortunately I could not get it to charge with the phone on any rom... even though the polarities looked the same as our batteries.. if only..

Yea the $4 one came in yesterday and after 36 hours I can tell it's not as good as the original oem. It's not horrible and will serve as a decent backup.. but certainly not a DD battery.. no way.
I'm more curious to give the 3500 a spin. Hopefully that arrives today.
Can't wait to hear about the 3.5Ah!
I have a 2.2, I think. Probably could last me three days if I didn't surf and play so much.
Edit -
I should mention that I usually end the day with about 50% left.
Today I'm already at 14% at 6pm because I watched two hour-long videos and did all the other surfing stuff as well.
Curious what you use to test your batteries with.
I run Battery Monitor Widget Pro and always wipe stats for a new battery. Great app for tracking battery performance.

Sorry, I haven't been able to test much. The performance was so crappy the few times I did use it that it hasn't left my shelf ever since. I know I said I was going to do standardized tests but I've been super busy the past few weeks.
As for the anecdote- I charged the 3500 up to 100% and went out for a night on the city at about 2pm. It was dead by 11pm and I was pissed. However, I'm not willing to pass judgement on it yet because I was running PAC at the time which absolutely devoured whatever battery I used.
Now that I'm back on stable CM7 it's a bit different. I'll charge her up tonight and do some comparisons this weekend.
In my experience a battery needs to be exercised a few times before it "matures".

You're probably right. I'll have some more definitive results on Monday.

I bought a cheapo battery for my G1 from my favorite cheapo Chinese stuff website - dealextreme.com.
I think I got an extended battery for my OG Droid there as well, long time ago. They were ok.
I absolutely love big batteries. And paying as little as possible for them.
-MROM on DInc2
So I don't have any definitive results. Overall the 3500 does last longer but not by much. I ran it from 100 to 1 twice over the past week and made sure it received standard use and no charges. I have attached 2 screenshots of the drain plus one with the top culprits for drain. Like many 3rd party batteries it tends to take a nosedive once reaching ~18%. You have maybe 10 minutes left when it hits that mark.
My workplace has horrible signal so cell standby is probably much higher for me than it would be for most. For comparison, my OEM lasts about 14-18 hours without a charge.
Bottom line:
3500 mAh linked above- You can't go wrong for $9. It performs like a ~2500mAh. the case is good quality too.
1500mAh linked above - might come to the range with me next time for target practice. That thing is worthless and is maybe good for 4 hours of standard use. Streaming a 1 hour playlist from Google music used approximately 40% of the battery.
Good to hear.
It's sad that we can't trust the ratings on the batteries, but I am glad it worked as well as it did and that the cover was acceptable, too.
I've read a lot of battery reviews on Amazon and even then it's a tough decision to make. Like you said, for the $9 it's ok.
I'll never buy a $50 battery, but if I did I would certainly expect it to perform to the advertised spec. Sadly, the reviews on those batteries are as mixed as the reviews for the cheapies.

Some interesting information
Bought similar battery a few months ago. On standart battery I has only 10-15% left at evening (music, instant messaging and serfing drains battery wery well), with this enhanced battery my phone lasts 2-3 days. I attached the photo to compare it with default battery.
The main disadvantage of it, suddenly, was the incredibly low signal level (only 1 bar on WCDMA in wooden house, 2-3 bars on GSM), problem was in antenna that is located at the down of back cover. As you can see, two contacts was joined. Just split them, and signal should improve. It helped me, but not too noticeably. So, I have to put copper wire on the back cover and even to prolong it beyond. It looks very ugly, but now signal level is even better than on stock battery (always full signal level on the street even in 3G mode). Low signal level results in higher battery drain and heat.
I don't know why HTC decided to save money on antennas in our phone. Because stock battery cover GSM-antenna is worse than any Nokia (it's much smaller, but in antennas, size matter, a lot). Wi-Fi antenna is bad too.
Also, battery indicator in our phone is not works as it should, I think. 0% is actually not zero level. Real Lithium-Ion battery zero level is 3.2-3.3V (sometimes even smaller, but it's not recommended to to discharge it beyond this level, it may damage battery), but HTC controller tells 0% at 3.5-3.6V and Android forcibly powers off the phone. When I used De-Sensed V firmware, where Android power off function on zero battery level not worked (may be, it was disabled in services.jar, there is the way to do this thing), I could run up to one hour in ICQ on 0% and even some hours in idle mode, before the battery controller blocked battery discharge to protect it (voltage was around 3.2V). It's disappointing that I can't make an urgently call while I actually have the power level enough to do this.
Thank you! Very nice to read your solution for the antenna!

I have good luck with my antenna, so I doubt I will have to do any fixing.

AckerMAN_ can you give more details about your antenna fix?
I see in the photo that the cover has two plastic fingers that are painted with copper colored paint.
My cover has metal fingers attached to it for the connection. They are like springs.
Can you attach a photo of your antenna wire, please?
This phone is famous for poor signal and many others would be interested in a way to improve reception.
-MROM on DInc2
There is a photo of back cover with attached wire. Also, I attached the screenshot of current reception level. I hope it will be useful.
Also, I'm thing about patching services.jar, I'll try it when have enough time.
I remember that when the S9 series made it's debut, Samsung claimed their batteries would degrade more slowly over time than the competition, even to the extent of claiming only 5% loss of total charge in the first year vs the 15%-20% that you can expect from pretty much everyone else. Now that the phone is a year old, has anybody been monitoring your real capacity with an app like Accubattery to determine whether this can be confirmed or not? I do not have an S9, but I was thinking of switching to Samsung when the 10 series is released soon if they were truthful with their claims of more resilient batteries, so thanks for whatever results you can share.
And you believe that app will actually know the truth?

I know it will give a better estimate than the original claimed capacity because it degrades over time
I do. I generally charge as all those articles and AccuBattery suggest that is trying to keep the battery from extremes, usually charging 40-90%. And now AccuBattery says my battery after 7,5 months is at 82% its original capacity. I would like not to believe that but in actuality I see the battery is not really good as I barely make it through the day with medium usage (usually some 3h SOT and I actually have few apps and use the phone for communication and reading mostly). That anxiety makes me think of switching to Oneplus 6T - though I would miss wireless charging I value the lack of battery anxiety (guess that is a psychological term already ) more. I know I could just replace the battery, but it was average at best even when new so no point.

And how does it know how much it degrades? Does it know the chemistry of the battery in the s9? Its a guesstimate, nothing more.

Thanks for the feedback, I'm not surprised the term has come into use. I probably sound like some kind of conspiracy nut but I am sure the manufacturers design the phones with planned obsolescence in mind by only giving them the minimum amount of battery they can squeeze since they will go down the toilet over time anyway. I'm on verizon but I was thinking of switching to the moto g7 power edition when it comes out for the same reason, especially considering how samsung seems to have lied outright about their supposed better battery longevity.

For a self proclaimed "provider of experienced replies", you really don't know what you are talking about. You don't need to sample the battery chemistry, the current the battery provides over it's charge cycles are what is necessary. The app takes approximations of it to determine how much current output it can sustain over time and that is it. Sure it isn't a 100% accurate but I'll take it over a the nay-saying ramblings of a whiner on this forum any day.

Unfortunately that's what it seems and it's a great shame really as S9 is pretty much a complete package in my eyes. Anyway, it seems I might be selling it and gonna miss the heartrate monitor and One UI (really liking it), but pumping the phone's battery 2 times per day is not for me in this day and age and that after only 7,5 months of usage Next try S11 maybe.
As for AccuBattery method - from what I understand it measures the current flow when charging and compares it to the percentage of battery charged. This way it knows e.g. that the battery got 40% charge over 1000 MaH charged which would mean (as in my case) that the battery's max capacity would be around 2500. Of course it's not perfectly accurate but it makes sanse and shows you the direction the battery goes. Ah.
