S9+ battery life

[KP8819]

I took my phone off charger at 6:30 AM and back on charger at 10PM, so this is what apps are running the last 2 days. I'm running Bluetooth playing Iheart radio all day, some web browsing, a few phone calls and about 1 hour of playing billiards. I was good all day on battery, still had about 10% left when I put it on the charger. I'm impressed with the battery so far!

I have the S9 not plus but didn't want to start a new thread for it...

I'm getting close to 20hrs battery time usually more when not using as much & less when more but never less than 18hrs - with 6+ hrs SOT. I'm quite happy personally & dont understand the negative reviews. I'm using WQHD+ & Atmos, adaptive display, keep high accuracy local on & game occasionally...

Am I delusional thinking this is great battery time? (At&t 845)

Why do I not get any luck with any Samsung Phones with battery life? 11 hours at most, if I am reserved. As we speak, it's back on the charger and it was off charger for only 7 hours.

What can I do to determine what is draining my battery?

Don't sweat it. A Lot of it also depends on your signal strength. Check out the battery usage section on your phone.

That's what I'm starting to think. I'm on att but have very good coverage. Both at home and at work.. work moreso since the tower is like a few hundred feet away. Could it be the cell signal? How do I determine the strength of the signal?

Cell service in your area, work, home, etc. Background apps, email accounts synced, location services, wifi and bluetooth always on while not needed. Theres many factors

I've had my phone off charger for over 25 hours now, actually using it... Wifi is turned off today, but not for battery life reasons, using Bluetooth actively - very happy with battery life relative to my S8 (even with the Oreo update)!

Took the 9+ off charger at 7am and 9pm this is where I'm at. I'm switching back to my Note 8 for tomorrow and see what battery life is like on it with the Oreo update.

I'm getting about these results with my s9. The only thing I don't like about the phone. I came from an LG v30. The v30 kills it hands down

My experience so far is approximately 6 hours of SOT over a 16 hour day. The s9plus has been consistent so far and a little better than my Note 8

Worth it to upgrade from note 8 to s9+?

Have the 845 processor s9 (not plus) here on Verizon, some days I get very good life, others it's less than a day. For me, the amount of time on calls appears to be a big impact (note I have HD voice on, which I believe means an active LTE connection whole on calls). If I have an hour or more of phone calls, then I don't last a full 12 hrs.

Also, I think exchange email/calendar/contacts drains battery. I use the Samsung native exchange server app (versus the Google one that runs through Gmail), connected to Office365 server. Has anyone tested each version of exchange to see which one has better battery life? I did a long time ago when Gmail app first started natively supporting exchange, and it didn't seem like much of a difference back then.

My 845 9+ lasts the same as my 835 8+ did, which is for me, very good.

It would be real handy for folks to state which chipset they have. 845 or 9810.

This came out today. Appears the 9810 INTL version is facing challenges.

Wish it was the other way around.. because I have the unlock Snapdragon and not getting good battery life.

The Samsung version drains so much battery.

Depending on the person, could be an easy fix IMO, at the cost of performance. At least until a firmware update. Basically the trouble appears to be in single core operations at high performance, when the chip ramps up beyond 2.3Ghz. Turn on mid power saving to throttle the CPU to 70% performance. The chip is supposed to be 30% better than the S8 chip, so basically you get S8 performance.

Of course the problem here is just more of an optimization issue, so an update should fix it. At this point, just seems to reiterate how it's not really much of an upgrade over the S8. But if you're coming from an older device it's still pretty worth it.

My Verizon 9+ gets same good battery life as my 8+ did. Wonder what could be different?

The reason though for the governor juggling is the chip apparently runs hot without it. Hopefully tweaks mitigate the issues, but seems there could be a systemic design issue with the chip. Seems all the tweaks would do is provide same battery life as previous chip by making it the same overall speed as well.

My S9+ SD845 is a quite a bit better than my SD835 8+.

2 days with S9+ ...Battery life is superb compared to my Note 8...really happy as of now....happy with the size of the phone also...and stereo speakers are awesome...

Tested battery life on my S9, after 24 hours with a few calls, no video streaming battery is at 70%
