Hi
Mine does about 1 day if I am lucky, WiFi use fries it. This is about what I expected.
The 'time left' meter on the today screen starts at about 4.5 hrs and seems pretty accurate.
If I switch off the auto-off and leave it running with wifi on then it gives me a low batt warning (@ 20%) after about 5 hours. (wifi on, Beams off, backlight off after 30 secs, bluetooth off).

Extended Battery??
Standard battery is 1450mAH. Does anyone know if an extended battery exists?
Nigel
U may want to buy this if u want a really "power" spare battery.. but cost quite high...

Hi,
The battery life depends on how the device is used. In my case, with phone signal strength at full bar and without incoming or outgoing calls and not usage and stationary, the battery will last 48hours on a full charge. With Wifi on the drain on battery is fast, I am getting about the same figure as you have indicated. I also notice that the phone radio draw more power if you are on the move and in some instances I have notice that it draw twice the amount verses staying stationary scenario. The comparison is based on no incoming or outgoing calls.
Hi
Yes, the radio will draw more power if you are on the move. When stationary, the device will tell a base station (BS) that its there, and then there will be no further comms until say 4 hrs time (the time depends on network config), when the BS says 'hey, device X, you still with me?'.
When you are moving, things are very different, the device (MS) will be handed over from BS to BS as you travel. Sometimes there will be 3 base stations serving a given area, the MS will communicate, and return QOS info to the network to decide which base station it should use. This can happen pretty often. A Hand-over occurs when the signal from a new station exceeds the signal from the old station. There is some hysteresis applied to the handover to ensure that it does not swap between 2 or more BS that offer almost identical signal strengths but regular flipping from BS to BS can still occur. There is much more to it than that of course...

Hi
This is listed an an XDA II battery, not a IIs batt. Dont know if there is a difference, I have emailed them to ask if it fits the IIs.
Thanks
Nigel
well my battery lasts for 2 hours full use... and 24 hours standby on flight mode with no bluetooth...
I have the XDA backpack. With this I experience 3 days standby and about 1.5 days on regular (about 30-45 minutes of call, and about 100 SMS messages sent and received combined) use.
Poch
Hey XDA
I'm having absolutely HORRIBLE battery life with my GIO. I've gone through extensive testing to find the root of the problem but nothing seems to be the cause. So far i've had to charge twice, maybe three times a day.
So here's the story. A couple of months ago I noticed my Gio's battery was dying quicker so I flashed another rom [Particle Mod] over it. I was happy, until I found out the problem persisted. Then I flashed a 2.3.7 Cyanogen mod, the battery still wasn't lasting and the battery life was only slightly worse owing to CYMOD.
I then flashed the GALAXYICS beta, and it's getting even worse. I've even bought new 1600mAh batteries to see if it was the battery's fault. Apparently not, so I went back to stock for a day or too to see what it was like, and I was still lucky to get 12hrs out of it with featherweight usage.
I simply do not know what to do, I've tried numerous battery mods [flashable zips etc] and they've only done a tiny bit. Lately I've been playing with clockspeeds but it seems to only make a difference if I raise the minimum speed, the extra top end performance is nice though.
So, what I'm saying is this normal for a Gio? Is it a hardware fault? software? 4th dimensional? I'm at a loss, and I think the infamous Samsung cell standby drain is to blame.
Attached is screenshots of general battery screen, Cell standby and the Graph. I've been switching between 2G and 3G, Airplane mode on and off, and listening to music for an hour or so and It seems to have utterly crippled the device doing simple tasks, and I've done EVERYTHING to minimize the drain by lowering screen brightness to %0, turning off vibration, animations, wifi, GPS, BT, radio, everything except google contacts sync and a couple of root things in between like deleting the batt stats.
The new batteries help somewhat, but I still can't last long enough for a single school day... FFUUUUU!
I really don't want to have to buy a new phone, I'm only 14 so I can't work to get one, and I can't just ask my parents because then I'm just being a spoilt brat. I want to make this phone last as long as possible [Until I can work for a Google Nexus or something] and the battery isn't helping.
Thanks for reading.
Yeah you're a spoiled brat. This is not great but not extraordinarily bad. My epic 4g touch spends the day on the charger.

Well, it seems to be all right with your battery. And your '1600 mAh' battery was just a fake. A lot of people get scores like this
What I am worried about is not so much the capacity, it's the RATE at which it drains. I see a lot of "stair steps" on my graphs so I'm not so sure, especially when checking the other phones in the house "a Galaxy Ace and 2 HTC Incredible S's] they seem to have a more consistent curve, I notice my batteries will drain by as much as %5 in half a minute, which is either a reporting bug or inconsistent strain.
Have you tried to do a wipe and test it with no installed apps?
Do not trust the "stairs", it is just bad reporting (as you said).
In my case when I switch on 3G or WiFi, it happens that the battery drops by 10% instantly.
The only value that is relevant is the total duration between a full charge (100% charge + several hours still plugged) and the "low battery" indicator.
According to my own experience, the things that drains the most are :
- 3G network : this is the main factor, by far.
If you can, try to stay in 2G mode most of the time, switch to 3G when needed, and as soon as not needed anymore go back to 2G.
- WiFi / BT
If you switch On/Off very often, or is always On and you moves very often (changing hotspot), then WiFi / BT will be a very important battery drain factor.
- Multimedia
Videos / MP3 drains battery a lot.
If you can, switch to "airplane mode" or switch off the phone during night.
Finally, with 3G / WiFi / Multimedia usage mix, a "One Day" autonomy is good.
I'm sorry but you will not find any smartphone that can pass "One Day" with that usage type.
With my own usage (very few calls, sms, wifi) and with above tricks, my Gio lasts 4-5 days.
PS : As you mentioned, available ROMs are very unequal as far as battery drain is concerned.
Stock ROMs (and moded ones like Adrenaline) are the champions of battery life, while ICS ROMs are the worst.
CM7.2 ROMs are in between.
I agree with Vilo76. When you don`t have wireless or 3g, or play any music/games, you can actually get a few days of life from your phone, but if you do some of the stuff i just said, the battery life is going down like crazy...
The only think you can do to get some bit of juice out of your phone is if you format your battery, but actually that is just for a better battery reading, not actually extending your battery life...
By the way, I can't figure out why phone manufacturers don't use more long lasting batteries ...
There are many many examples of batteries that are about the same size as a phone one, but deliver way more mAh.
Among others :
- House wireless alarms keypad batteries are the same size but can be as much as 3000mAh ...
- Classic cylindrical AA or AAA accu can be as much as 4000mAh ...
While a typical phone battery hardly ever exceed 1500mAh.
Okay, I'm back and I have some results for today
3G Is DEFINITELY using more in Australia on idle, while 2G is a bit less brutal
There is something cause my phone to wake intermittently, I've turned sync and location services, and killed any apps that may be checking the net etc, but it's still waking up with screen off.
---------------------------
Today I decided to do something bit extreme, I ran the phone an airplane mode all day with the original "dead" battery, I only lost %20 all day with 1hr or so music usage, phone standby is up but Cell standby isn't there at all [Obviously].
Something's telling me that's it the cell radio and whatever is waking my phone up is causing the suck. I'm upgrading to GalaxyICS CM9 beta10 today with a full dalvik, battery and cache wipe, so we'll see how that goes
----------------------------
MORE NEWS
Good news this time! I've installed a Cyanogen Mod 7.2 on their [The one that's updates through Goomanager] and the battery is holding steady at 100 idling for 1hr on 2G.... Not sure if I have to calibrate but I think I've fixed it, it's working better than stock!
Hey guys 2nd day with moto 360, battery only lasted about 8 hrs... Wondering if the wifi being on is a culprit? Maybe constantly searching? I can't seem to find a way to turn it off? Went through settings etc...
yes, wifi will flatten this battery fast! there are other threads to speak on the wifi use, with all due respect, no need to start another one.
look in the battery stats in android wear app and see how much battery power is going to it...
'course could be a rogue app or watchface as well...
Just want to know your thoughts about having wifi or Bluetooth enabled all the time, even with no connection or pairing with nothing, regarding battery life
I ask this because my test would not be accurate as I always use the phone differently (moving to different places, calling, music) apart from playing with kernel and other settings... So can't really tell the difference in that
Please don't tell me, just turn them off when leaving home or leaving your car. My point is to get it connected/paired with no need to unlock phone, turn on... etc... xD
About NFC I saw a module to enable it when screen off. But I read comments that it causes big drain, obviously
On the previous build MH19C I was pretty sure if wifi 5GHz is enabled and available, it will drain and also wake like crazy. This happens in my office but not at home where I don't have a 5GHz wifi or even wifi ac, but is widely used in office, with multiple physical AP's. Now already on the May update, I no longer enable 5Ghz wifi and backgroud scanning just to be safe.
Less than other devices due to the Android Sensor Hub and Doze.
while not in wifi i have data which drains tons of battery anyway, so i dont even bother with any miniscule effect wifi scanning might have. i would advise you to put it off your head too, there are thousands of tiny unessecary battery drainers in your phone, it would sap your mental health trying to deal with anything more than the big ones (data/screen/bugged apps) for only few % of battery.
if the phone is able to last till bedtime or return to home, then it does not matter to meddle with anything. charge it every night and if comes to worse it charges to 50% in few minutes
Thanks for responses

Exactly, that's why I want to know if the % is noticeable or not
It's a good advice. However it's also good to keep things in order because battery cicles are limited in phones and my goal is to keep the 5x more than 2 years xD
So I wouldn't be fine just getting at the end of the day, it's good to preserve and not drain unnecessary drain, considering this battery is not removable, plus it is already 'bad' being new haha

i dont know about battery cyrcles, but replacing battery on 5x is not hard - watch a video about it as to not make any hasty mistake, and its piece of cake.
also its better if the battery is not too low when recharged and not too hot. 5x already has a annoyingly protective temp threshold so you dont need to worry about ruining your battery that way, while its better to recharge every night (or more often if you need) even if there is plenty of juice in the phone cause that is healthier for the battery.
If reducing battery cycles is your main goal, you have to turn them off.
I'm keeping wlan (connected at least 50% of the time with decent-v good connection)/bt (most of the time no connection, only in car and for bt speakers) switched on all day and they together take 7-8% battery on (my) average use (~10-15% left before charging every night), of course much less (in relation) when heavily using the phone.

That's what I wanted, some numbers about your experience
Fine then. Once I get some rom and kernel stable I will check for myself. For now it will be disabled when not using (tasker helps too)
Hi guys!
I have a serious problem with a used A5 (2017) I got from some friends. The battery life is abysmal. I already changed the battery and it didn't change anything.
It is running on Android 8 Oreo. The most serious problem, I think, is that the phone even discharges when it's powered off. I tried using the latest hadesrom, but it didn't changed a thing. Lifetime is around 12hours, doesn't matter if I run some apps or just let it lie around in standby. I tried factory rests and some battery saving apps... nothing works. Is there any way to get better battery life? Thanks in advance!

You could try the naptime app. But I don't think my battery life is any better than yours.
The a5 2017 has a famously good battery life.
I am not a heavy user - make and get few calls and mainly use it for receiving emails and a few texts plus a bit of web browsing.
Occasionally listening to podcasts.
3 days battery life is easy for me - reckon I could get 5 days if I just left it sitting quietly.
If it's going flat quickly even when switched off, it sounds like a fault somewhere.
Don't know what else to tell you.

I never tried letting it sit, but if I just left mine alone it would last for days too. But if I am gaming on it, it will go down to around 50 percent at noon.
wow - 3 days life battery!! I can hardly get to 2 days, without heavy us - but I would never try to change the battery -> sounds too complicated
One thing that is worth looking at is the Always on Display (AOD).
I found it sucks a lot of power despite the claims that it 'doesnt use much'. It seemed to use around 1% an hour - I guess thats around a quarter of your battery in a day. So unless you find it useful either turn it off - or set it on a schedule for when you actually want it to be on.
Battery life is always sujective and depends on what your phone is doing - gaming will burn through a battery like nothing else.
The OP said the battery drains even when the phone is switched off - That sounds like a hardware fault. The battery will gradually drop when switched off - but it should take months for a healthy battery to drop much if the phone is switched off.

1 percent an hour doesn't matter to me lol. I am a heavy user so I charge every day anyway.
