[Q] Is there any way to determine your battery capacity/health?

hi guys, as the topic name suggests, is there any way to determine your battery capacity/health? i ask this because my phone (and battery) is well over a year old now and i understand based on my reading that with multiple charge cycles, the battery health will degrade.
this is relevant because of late i have been experiencing increasingly poor battery life (though i think it may also have to do with the recent change over to ICS), i have no idea how people manage to get up to 4 hours of screen on time, as it is i can barely hit 2 hours with light-moderate use, much less playing games/watching videos.
Is there any way for me to check if my stock battery is still good to go? because if not i am considering getting a battery off ebay or buying a replacement battery from samsung.
thanks in advance

I don't know about capacity but you can get your battery health and other info by dialing this on your dialpad:
* # * # 4 6 3 6 # * # *

You can also check batteries voltage using that code. Or do it manually with a battery testing device or multimeter. Fully charge the battery, remove from phone and test voltage. If the voltage is a lot less than the one displayed on the label (I think our batteries have a 3.7V), then most likely your battery is starting to go dead.
Others thing you can do is to check if any app is running in the background (whatsup, skype...etc). Remove unwanted services while not being used: bluetooth, wireless, NFC, etc. And try a different kernel. I've heard Matr1x kernel is one of the best in regards to battery life.

Over the course of a year it is standard for one of these batteries to lose up to around 20% of their charge, unlikely very much more. If you think you've gone from ~5 hours screen time to under 3 hours i'd be looking at a software culprit or seriously dead battery, though the former definitely first as it can effect a new battery much the same.
As always, BetterBatteryStats (get it from xda) and CPUSpy can provide some insight into any software abnormalities causing excess battery drain.

thanks guys, ill try using the multimeter method, been trying all sorts of kernels with the latest cybergrmod ics rom. dont think i see much of a difference between air kernel and matrix (though the latter does give me reboots)

Battery sucks! Faulty unit or crappy software? HELP

I have used this tablet for 2 days now and almost everything works perfect (thanks to latest ota) but there's one thing that is bothering me. Battery life. I had ipad 3 for 2 months but I finally sold it and bought the infinity. Now I know ios sucks on phones AND tablets. But the battery life was amazing. I could use it to browse and for games for 9 hours at least. But on the infinity I am lucky if I get 4 hours browsing. 4 hours sucks on a tablet. But I think that wifi is the problem. I have added 2 pictures were you can see I used the tablet for 1 hour last night then I used it for almost 3 more hours today. Now the battery is at 10%. But I was wondering why the battery uses 62%? On my galaxy nexus wifi is using 5%.
Have I got a faulty unit or is it like this for everyone? If so please let me know fast so I can send it back before it's too late.

Somethings not right there. Tests/reviews done by some major outlets (thinking PC World or Engadget) reported 9 hours of video play over wifi with screen at 50% brightness. iOS has always had good battery life due to their stict contols over the OS, but you should be seeing more then 4 hours. Hell I was at 40% and played WindUp Knight for hours straight last night which takes up much more battery then a movie. I usually don't suggest using task managers, but there is one built in by asus, I'd use it and see if you can kill some processes. Also be mindful which profile is being used. I stick to balanced most of the time and switch to low when the battery starts getting low (24%ish)
http://www.engadget.com/2012/06/25/asus-transformer-pad-infinity-tf700-review/
The TF700 packs a 25Wh battery rated for up to nine and a half hours of runtime. Indeed, it lasted nine hours and 25 in our battery rundown test, which involves looping a video with WiFi on and the brightness fixed at 50 percent.

Thanks for the reply. I am always on Balanced and i am seeing over 20% down in an hour. Maybe i have a faulty unit?

I wouldn't be so sure. I was playing nova 3 on performance mode though.

Exactly, it all depends on what your doing OP. The movie scenerio in the review doesnt take much juice in that it uses the low power single core. I don't know for sure, but web browsing may require all 4 cores to kick in depending on exactly what your doing. Regardless, your wifi being a big consumer is easy to deal with. Somewhere in the settings is an option that automatically turns wifi off when screen is off.

Well, all i was doing was using chrome... I think it's pretty bad when i cant browse for more then 4 hours on a tablet. I thought it had to do something with WiFi since its using over 62%. I did the same test with my nexus where i i just used chrome and when i looked in battery , wifi only used 10%. Maybe there is a bug with wifi?

Try Battery HD for some averages/estimates.
I tend to get about 9+ hrs of reading, balanced mode, WiFi off, and about 7 hrs of browsing over WiFi (undocked, dock charges me about 2/3 full), but it all drops down drastically for gaming, which is about 4 hrs you mentioned.
If you get 4 hrs of pure browsing, I'd consider re-flashing, wiping data and - if these don't help - returning your device.

Chief Geek's point has much merit, and you could always look at (for example) GreenPower or some other time-/screen-based toggler. They do pretty well, and you do not even lose out anything except direct push functionality. (Does it really matter for 99.9% of mail when it comes in once every 15 or 30 minutes? When it does (when you're buying a house or something), shut down the toggler for the time being and cope with some battery drain, then when the situation has resolved, enable it again.
And try using BetterBatterStats for your statistics -- the main battery stat app Android offers has some quirks to prevent meaningful interpretations of many scenarios. Let that get a few charging/discharging cycles and then look at the stats.

So battery hd tells me I should get 8 hours of browsing and 9 for video playback. Will do another test tomorrow with screen on whole time and see how long it will last watching videos. Also battery hd tells me I can play 3d games for only 2 hours. Eh

Remember that these are just averages for your device, at least in the beginning.

If you mistreated your battery upon receiving it, it can kill battery life. You are suppose to plug in your asus tablet for at least 8 hours (well beyond the tablet would say the battery is 100%) the first time you get it. This is sound advice for any new Lithium Ion Battery.
Then you can start using it. Letting the battery die at 0% also decrease the life of the Li-Ion battery every time it happens (ignore old sites that say you should do a full discharge cycle every 2 weeks, that was for old Nickel Cadmium batteries).
Juice Defender is typically a phone app but you can run it as well to detect if any background processes are eating up your battery life.
I get almost 10 hours on my TF700 with moderate usage (mix of browsing, video playback, reading, etc.).

All correct -- there is a lot of disinformation going on with batteries (especially regarding the charging cycles, although a single, long, full charge and then draining to zero charge actually helps calibrate the battery indication algorithms in the device). The optimum minimum charge level seems to be about 40% or so I've read.
Juice Defender and Greenpower toggle WiFi on either time- or location-based profiles, and that works on tablets as well. Recommended!

Your phone doesnt actually discharge a battery to zero. The thing with lithium batteries is they maintain voltage untill nearly the end. This is a very large benifit for modern devices. Once the voltage starts to drop the phones circuitry cuts it off and prevents it from powering on with the LVC circuit that checks the battery before allowing phone to power on then immeditately cuts it (first attempting a power down then all out power cut). This happens to protect the battery. So what the phone considers a dead battery is simply an exhausted battery ready for charge. If a lithium is actually dischardged completely it will damage the cell and prevent it from taking a charge. The power being given to it is then converted to heat. The battery then ignites and very very bad things happen such as your house burning down. The point of all that is to point out that discharging your phone to "zero" isn't actually doing any damage past the normal wear and tear on the battery. I buy batteries that cost hundreds for some of my RC hobbies and have learned the hard way about how lithium batteries work. (bypassed LVC and ruined a $80 3S2P pack)

i have actually read that Li-Ion batteries can be used out of the box. Sp i turned on my infinity right away. I put the charger in, but i still used the tablet. It was about 25% when i got it out of the box. So what you're saying is that i have basically ****ed up the battery? If so, then i will return and get a new one. But i dont understand why most people say that you can usre a device with Li-Ion battery staright out of the box without needing to charge it first.

Nothing to add, technical and extensive, but fully correct, sir. I think we may have had a slight misunderstanding, however: my point was that discharging your phone to 'zero' (and as you rightfully point out, that is not an actual fully discharged battery state) is a required step in calibrating most device's algorithms (some devices, such as my SGS2 do not need this because of advanced hardware). I'd rather not fully discharge any Li-Ion batteries either.

A typical case of RTFM, an affliction I sometimes suffer from as well, as do most men. Hahaha! Do you think ASUS put it in the manual for laughs, or just to give you a few more hours of painful desire to use your device while you cannot, yet? Nah, it's there for a reason. Sometimes, though -- and again that's SGS2 experience -- just running a few battery cycles might make the readout correspond to the actual battery level again. You could at least give it a try, right?

[Completed] Massive battery drain for Samsung S3 - tried most solutions on the web

Dear XDA experts,
It seems I have a typical problem for most Samsung Galaxy S3 I9300 users. I've been testing my phone's battery capacity on two different batteries, and four custom roms, yet something leeches out their power incredibly fast.
I've been deeply investigating the issue across the web, with no prevalent solutions that worked. Below I will describe exactly what my problem is, my specs, and what I've done to this point.
This will be my first post. I'm only doing this because I want to bring BetterBatteryStats data into consideration, without just speculating "do this". Please have mercy on my soul - I really appreciate all the stuff on the forum, and I wouldn't like to violate any rules.
Problem
My Samsung Galaxy S3 I9300 drains my batteries as a vampire, regardless of what I've tried. Just to give you an example: the phone loses 6% out of a 100% in just 40 minutes of standby, while being optimized, with no "lost signal" search processes. Without charging it twice a day, the S3 remains mostly unusable.
Purchase and Specs
I'm its second owner. The previous one sold it to me through an auction site (he was changing to S4). The phone seems legit. Mint conditions, little or no scratches visible. The system was factory wiped, and later it turned out that it wasn't flashed before. I also got original Polish carrier boxing with instructions, and equipment.
Note: The guy didn't handle the receipt to me, and I don't know if there's still warranty on the phone. Servicing might not be an option.
System:
[Cannot upload - all files in a MediaFire folder. Please look over there. Just add the missing characters]
www (dot)mediafire(dot)com(slash)folder(slash)wfb1spe9ez9al(slash)xda_S3_thread
SentinelROM 6.00
3.0.64-CM-gfab9e4c Kernel
Android 4.4.2
Factory battery EB-L1G6LLU 2100 mAh
Second battery M-Life ML0373 2300 mAh 8.5Wh 3.7v Li-ion
Normally, Bluelight Filter and GoLauncher EX Prime are the minimum that I have in the background.
What I've already done
Rooted my S3 with CM Autoroot
Installed CWM Recovery 6.0.4.6
Always did a factory, cache, and dalvik wipe
Tested CM11 NIghtly from 09.12.14
Tested CM10.2 Stable
Finally flashed SentinelROM 6.00 4.4 KK
Debloated my phone - not syncing, no tracking
Disabled "All, that's Google" #notonmywatch
With every new ROM, I've been optimizing settings and tweaking the CPU to ONDEMAND. Also, same time I've been running Go Power Master and Greenify. That covers nearly everything people were recommending in the many threads I've visited.
Weird facts
Phone can lose 6% in 40 minutes after charge while idle
Writing an sms can take as much as 10% of the battery
It seems odd that the S3 can fully charge in just 1h on both batteries
When trying to discharge my phone, it deadlocks below 4%, lasting unusual 2.5h when used
Screens
I've been monitoring my phone for a day with BetterBatteryStats while I had Greenify hybernate some apps. Obviously, I've seen an improvement in the performance, but it just seems not right. There's a lot of pics here, but I hope that someone can spot a tracing app, or some other spying tactics, because I just can't explain what's on.
[Cannot upload - all files in a MediaFire folder. Please look over there. Just add the missing characters]

That's all I have for now. I think it would be a great favor to everybody on XDA to finally crack the case. I'm open to suggestions, and I can run tests on the S3 and provide results here.
Last question
Could someone recommend the best ROM and kernel for energy optimization?
Thank you, and good luck.
PS: Imagine playing Watchdogs with Aiden having an advanced S3 phone... Wouldn't happen

Your symptoms sound like bad batteries honestly. The biggest giveaway here is that the battery drains ridiculously fast to 4% then lasts the "normal" amount of time. This is usually indicative of dead cells.
My suggestion, buy another battery, avoid the cheap aftermarket batteries, either go stock or a good quality 3rd party battery and see if it changes anything.
How long between flashes are you allowing your device to settle? Battery drain may appear high on fresh flashes for the first few cycles, this could also contribute to what you're seeing.

Hello Stryke,
Did you had a chance to look through the screenshots? I might buy a legit Samsung battery, but just something tells me that could not work. I've already seen posts from people saying they tried replacing the battery with another original, but without luck.
I must admit that I didn't consider the time in between flashes as important (never heard about it previously). Normally, I would just copy my zips to SD, reboot to recovery, do a wipe and then flash.
Please tell me - what do you think about the charge time? Is 1 hour enough for a full charge?
I welcome any other suggestions!

Generally no, even with fast charge my note takes longer than 1 hour to fully charge. I'd try the new battery, that will at least rule out one possibility. Time between flashes can make a huge difference as well, especially if custom kernels are involved.

[Discussion] Battery Health

Hi guys,
as we are approaching nearly 1.5 years since the Pixel 5 was released, I am curious what everyone's Battery Health is.
You can use Accubattery.
BatteryGuru also has it included in their app.
It will take a few charges to get an accurate reading.
I take pretty good care of my battery, by never going below 20% and only gone about 80% maybe 10 times.
I just got Accubattery on my device so I will update where I am in a little bit.

Well since I feel itt'll take a good 4-5 charges before any type of "accurate" measurement is shown, I decided to do a full charge and I'm very happy, I feel like this is at least 90% the capacity still. Right now BatteryGuru is showing 70% but I expect it to *hopefully* go up, since accubattery is showing 85%, but this is only after 1 charge.
Running Android 11 crDroid v7.15

I did 1 full charge (35% => 100%) with AccuBattery, says my battery health is 93% (3 718 mAh / 4 000).
Not bad I guess, for a 16 month old phone which I used to charge regardless to "efficiency rules".
I used stock rom, and rooted couple of months ago. And only recently switched to lineageos 18.1 and elementalx kernel so I can't tell if there's a difference.
I'll take a look at crDroid, but I can't help installing some google stock apps - force of habits.
If I see any significative change after some charging cycles I'll give an update.
Btw are you using a custom kernel?

Thanks for posting my friend! That's a great starting point, I hope that it only gets better for you!
I'll upload images from what accubattery and batteryguru are currently showing, now that I have a few charges completed. I hope to see a higher health.. but it could always be worse. I remember my htc 10 bring at like 70% at this point in it's ownership.. though Android wasn't as up-to-date with battery adaptivities.
I used to use ElementalX but since lack of updates for Android 11 I've been pretty happy with crDroid stock kernel. (Though I have used the last update that was out and it ran quite nicely before I moved fully to crDroid. So I may give it a go and see what type of battery I am getting compared to crDroid stock).
CrDroid also comes with PixelGapps installed, which I personally love. So you'll get Pixel launcher, Camera and other Google apps/goodies .

I am not a very patient man, and a few minutes reading about this rom convinced me to try it asap !
Love it so far, I really like the stock experience with easy tweaks possibilities - I also already shared my gratitude and first issues in the main thread
I'll keep stock kernel for a few weeks and share accubattery and batteryguru screenshots here, before giving a try to elementalx kernel and see if there's a difference

This is all stock with root and some modules installed. I received my device in November of the year it was released

Just kept my battery charged between 80% to 20%

90% here. Have the phone almost since launch and accubattery since then. Don't follow the 80% rule too much. I use to follow it religiously but then read a comment somewhere that by following it, you are at 80% health effectively so... it made sense.

So after few weeks I'm 90% on Accubattery and 85% on Batteryguru. I did noticed the stats were pulled down when I charged only to 80%, so I would tend to agree...

I installed ElementalX a couple of days ago, I've let it just as it is out of the box, no personnal settings. It seems to be very efficient with battery usage but maybe too much because I don't receive whatsapp calling notifications anymore, only "missed call" once it's too late... gonna take a look on the official topic to check it out.

Thanks for posting!
I am at 90% myself actually, and noticed it actually went up from 88% to 90% when I charged it over 80% to 85%.
So maybe with all the new changes and upgrades to batteries, etc, charging to 100% is just fine?
I think it is the charging overnight for more than 8 hours can possibly be harmful.
I think I'll start charging to 90%.
Maybe try adding whatapp to battery optimization, is you haven't already to see if you start getting the notifications.

Already tried that but thanks for suggestion
About battery, I'm far from being an expert but I think it's still good to charge up to a lower lever eg. 80-90%, in order to preserve battery health and loose less capacity at each cycle. However, in order to properly measure the battery's performance, you'll have to give it a full charge or the stats will be inaccurate, as @ribogushter mentionned.
I would suggest, wipe your Accubattery and/or Batteryguru stats and give your phone a full charge from 20 to 100% and see if it impacts your health score

I think I will keep my stats in accubattery as it gets better with time, but I will charge it to 100% and see if it drops, goes up, or just stays the same at 90% health.
Edit: both accubattery and battery guru dropped a bit after charging to 100%.. down from 90% to 88% accubattery, and 89% to 86% battery guru.
I think I will probably do 90% from here-after though, I still think charging all the way to 100% all the time isn't the best, but I really don't know anymore!
I'd like to read more about getting the only 80%, I mean it's just common sense that you get actually only 60% if you run from 80%-20%, but that is charge capacity, not battery health capacity.
I do wish Google/Android had some documentation on this. Even cApple at least has a battery capacity built into its settings, and I saw they have a setting that tells if say the screen was replaced was it done using official cApple products, very good idea actually.
Also how has ElementalX been running?
I decided to flash it and see how it compares to the stock kernel in crDroid_v7.17 (Android 11)
I always loved it when I used it, but it is a little out-dated, (over a year now) but I think it's still fine.
Proton kernel is also really good.

I think it was becase I enabled data saving, and since I put Whatsapp on the exception list the problem seems to be solved. Once again, the problem was between the chair and the screen ^^

As you said, we probably never will have a 100% effective method to quantify battery health until it's native to Android ¯\_(ツ)_/¯

Really smooth, I'm not experiencing any lags or freeze, or any problem so far and battery life seems to have improved. As a pure rookie, I don't understand what would make a given kernel different or better than the other, so I tried the one that seemed to be the most popular but I noticed only afterward that it hadn't been updated for a while and that the developer is focusing on his apps (he mentioned it on some thread).
Proton kernel's latest update is also almost 1y old, I'll stick with ElementalX until next update or give a try to CleanSlate which seems to be the most active.
Btw, I guess you're using ACC? If so, which charging switch are you using?

Best way to measure your battery is to charge it with an USB tester such as UM24 or UM25 . You can see how much mAH your battery can absorb and calculate the health . Phone needs to be turned off and charged with a regular charger, not fast-charger .
I'm looking for a good benchmark for the battery , i tried Geekbench4 , PC Mark ..do you any other good ones ?

Not that I think it helps I am always on my PC and just charge through the usb-c.
charges pretty fast too, like 45 min.
I may invest into UM24 orUM 25, thanks @arcadekidflo

If you only use usb-c to usb-c you can get TC-66c , from the same company . If you also use regular chargers you can get UM-25c .

I accidentally charged to 100% again, and health went up in accubattery.
Maybe I will start fully charging..
Oh yea. One thing that helped for me for late notifications is to turn off "Adaptive Notifications"
-- It's been working for me.
some ROMs (such as crDroid) it turns it back back on after every reboot.
I just make a shortcut on my homescreen using Activity Launcher

Many thanks my friend! Very much appreciated.

Mine looks like it's around 94% - ordered it on release day, so about 1.5 years old now.
I've not followed the 20% - 80% rule, most of the time just letting the phone charge fully over night.
Maybe the 20% - 80% doesn't really make any difference?

IMO it's pretty silly to only use a portion of your battery's indicated capacity. The nature of lithium ion batteries is such that both over and undercharging can cause damage, so manufacturers don't actually use 100%, or even 80%, of their full voltage potential. The battery circuitry itself, as well as the phone's power monitor, do a sufficient job of limiting charge and discharge, so its really not necessary to do it yourself. Use your phone as you normally would, but be aware that keeping it charged all the time may reduce battery life.

Check for battery drain in my OP7 Pro

Hi everyone!!
I'd like to get some advice about my issue that I've been having for a while...
My battery drain is what you may see in my attachments. Please tell me some good advice to reduce this drain or whether it is normal functioning either...
In conclusion, I'd like to know if it might be convenient to replace the battery and, furthermore, whether there are larger batteries with more autonomy.
My phone is 2 years and half old but to be honest I use it intensively with its battery-case (manufacturer: Newdery).
Thanks!!!

Sorry for late reply, just saw this.
You get 6 hours of battery life with 14% screen on time? That doesn't sound to correct.
My suggestion would be to install the app: AccuBattery. I swear by it - it is very good I think. It will watch your apps much better than the stock android battery monitor. It will also tell you your battery health, the mAh left out of the total of 4000. If you have a very low amount left (capacity wise) then you may want to get a new battery. But make sure to do several charges before taking it as accurate. Use the app for several days, even the little "notes" in the app will tell you this - it's to "acclimate" to your use and give you more accurate statistics.
Hopefully this helps - 6 hours is definitely not good.

Hi!!
Thank you very much for your reply!
I forgot it but I already had Accubattery installed on my phone.
In fact, in attachment you have the battery wear data from April 2021 till now..
I hope that I shared you useful data to analyse the issue.
What do you think? What should I take from the app?
I thought that the new Android version 11 is the cause of battery drain as another phone (Xiaomi Redmi Note 10) suffers from it after the upgrade to Android 11..

No prob
Could you take an [extended/full] screenshot of the "Discharge" tab? That will show more info about which app is draining more. Also those numbers change I believe on every charge so you'd have to just keep an eye on which app is always at the top of the section under "Foreground App Battery Usage > Battery Usage" section. Hopefully it isn't just "system" or something, hopefully it is an app that you can remove/freeze.
And what does it say for Battery Capacity above the "Battery Wear" chart?
And speaking of the wear chart, you'll want to stop charging all the way to 100%, it looks like you're putting over 1 cycle of wear on the battery very often which will degrade the battery quicker. The 'Charging" tab explains this even allowing you to set a reminder to unplug at a certain charge level (it tells you the higher you charge the more wear you put on the battery - unfortunately that's how batteries work).

Hi, thank you for your reply!!
I'm sorry for my late replies..
In the attachments you have what you asked me.
It seems that Facebook drains the battery a lot despite the fact that I don't use it much.
The battery wear seems to be almost one fifth of total capacity for a capacity of about 3200mhA.
I'd like to have something better...
I have set at 83% the alert to reduce the wear of the battery but I wonder how it could work fine when the phone is turned off..

No problem
So, I'm not exactly sure how you use your phone but it looks like the screen-on at 23%/hr looks pretty bad but then also it says combined time was 102 hours? I believe that means how long it's been off the charger. If that's the case you can't get any better battery life than that, that is really really good.
You mention facebook doing a lot of draining. Try researching a good app freezing option on the app store. I only did a quick search but this one came up: https://play.google.com/store/apps/details?id=com.catchingnow.icebox but read the reviews (I did a quick scan and it looks like it might work as intended) and look around maybe there is a better one. But the point of this is, to freeze any apps in that list (the accubattery foreground apps) you barely use and it will prevent them from running in the background. This will definitely give you better battery life.
And I don't see the deep sleep statistic, is that around 90hrs along with the screen off time? It should be more than the screen off time at least, because if it is then it is deep sleeping correctly (no rouge apps causing it to not deep sleep), but if it's less than the screen off time, then something (maybe facebook) is keeping the phone awake even with the screen off, causing extra battery drain.
And 83% charge is pretty good, maybe even 75% might be better, I think from 0 to 75 it's like .3 or .4 wear but it's like with these batteries once you start going over 75% it jumps in wear dramatically. And if the phone is off (turned off completely you mean?) then the battery won't gain any wear because it won't be in use at all.

I noticed that I didn't make all the screenshots, but now I've just done them with regards to this new discharge cycle and you have the deep sleep statistics for a better analysis - they are in attachments.
I asked here for a longer battery lasting and instead I set it as 75% as the maximum percentage value of charge that reduces my autonomy but saves the battery.
However, yesterday I noticed that the charging wasn't deactivated when the phone reached 80% of charge (is the value that was set yesterday). Oughtn't Accubattery deactivate the charging?
The statistics you mentioned in your previous post appear to me a bit awkward even though they are related to many sessions in the last 7 days.
I use my phone with my phone case-battery (Newdery manufacturer) and until few months ago it could charge the phone up to about 80 % when I couldn't charge my phone through its charger. I need the charge to last a day, almost 20 hrs…
I noticed that the phone started to wear - the last few months - when I noticed that I couldn't have the phone working till the late evening and I tried to charge it fully before I left my house...
However, it is clear what I need for my use and habits, thus, new reliable battery-case suggestions would be a good hint for me...
In the end, I don't know what to do about apps that manage the apps freezing because I don't know how Android allows it and if it is worth it..
