Help with battery issue

[ramses2005]

Hello, since a few weeks ago I have been noticing that my macbook pro 2017 has been having battery issues. I might have 20-30-40% battery charge left and randomly my macbook turns off , then when I press the power button the battery icon is displayed so I need to proceed to connect my macbook and then turn it on again. Sometimes it starts where I was (similar as powering on from sleep mode) and sometimes it starts from zero.

Supposedly I tried resetting SMC but it did not seem to work. Also battery is not malfunctioning and battery life is good.

I had the same problem for my 2015 MBP and I sent it to Apple. I had paid Apple to install a new battery a year before. It eventually got to the point that it would shutdown at 70%. A restart would show a graphic that there was no charge in the battery and that wanted to be plugged in to continue startup. After restart completion it would show the battery was at the same charge percentage it was at shutdown.

The battery capacity and status was good. I contacted Apple and they had me send it in since I thought it might be a problem with the battery they replaced.

It was a problem with the logic board.

Update: My batt has about 400 cycles and today, after resetting PRAM, VRAM, SMC, etcetera I still got the problema and now my batt says it needs replacement. Even though apple certifies batteries up to 1000 cycles

What’s the “full charge capacity” value (located a few lines above cycle count. The reason I ask is because even with lower cycles, if the charge capacity has been degraded beyond what’s normal, you can definitely run into issues lie, what you described.

It's more complicated than "Apple certified batteries up to 1000 cycles", if the battery drops below 80% full charge capacity and the cycle count is less than 1000 whilst in the warranty or AppleCare period then it's treated as a warranty issue, if it's not within the warranty period it's like any other out of warranty fault, it is chargeable.

Battery health can be affected by a number of factors (not just cycle count) including the way the battery is used (is it left on charge a lot of the time), the temperature and other environmental factors, and quite simply, the passage of time too. They're consumable parts and they will deteriorate over time.

Just because the battery has gone to "replace now" doesn't mean you have to replace it. But it's quite a good deal compared to most repairs from Apple, and will serve you well for another few years if you were planning on keeping the computer. But if you were planning on upgrading your machine soon, it's probably not worth it.

Full charge capacity: 3692 mAh
499 cycles

Ah ok, it looks like your battery is in bad health (even if it doesn’t give any messages). From my recollection a stronger battery should be in the 4500+ range for the touch bar model

Depending on whether you have a 13” or 15”, you can google the battery capacity for your model. Even if it’s a 13” you’re well under the value for a “healthy” battery.

If you start getting alerts that the battery requires service (or something along that line), might be worth it to get a replacement from Apple for $199 (US).

That's more than doing it yourself, but you get an Apple OEM battery, installation, and a short warranty. A pretty good deal, IMO...

Is it still $199 for the Touch Bar models? That’s what I paid on my mid 2015 for the battery/top case replacement. If it’s still $199 for the newer models that’s a great deal for what you get

The battery in my 2017 MacBook Pro was replaced back in Februray. When it get down to 34% I have a hard time connecting to my Wifi & WD hard drive. I don’t have problems with IMAC or IPAD. However when I plug it up and reboot it work fine. Help cause this don’t sound normal.
