Will the Lumia 640 battery fit and work in the Lumia 650?

Will the lumia 640 battery fit and work in the lumia 650?

I have the Lumia 650 and Band 2. I'm really happy with the devices but the battery life on the 650 is terrible, not even getting me through a day. I don't game, just average business use. Need a solution or the 650 just isn't viable as a device for me.

I don't think that could work as the the batteries would have different physical sizes. You could get an external power bank to boost the battery

A few things you can try out:

• Check settings >system > battery > which apps are using the most energy?
• Again, in battery section, which apps can run in the background? Can you disable those you don't need? Keep messaging enabled to run in background
• In battery section, you can also set up battery saver to kick in when the battery reaches a certain percentage. I keep mine on 100% so it's always on battery saver mode
• In mail app, how often do you have mails to sync? Generally the longer the time period, the less the battery usage
• What about brightness settings? Is it on high or auto? Auto is better than a fixed setting
• If you find that messaging app uses a lot of battery, this could be because it's linked with skype. Go to messaging app, settings and unlink skype
• In photos app, do you have auto upload of photos enabled? If yes, try to not upload high res photos and videos unless you are charging the phone and on wifi
• When you use some apps that are not data heavy like whatsapp or mail, you can use a lower network speed like 2G. It's what I do usually. I only use LTE when I have to use 6tag
• If you're using edge for basic browsing, you could try using UC browser. Not only does it use less data but you can also disable images which means you save even more on data. The less data your phone has to receive, the less the energy used
• In settings > privacy - check each of those settings to see which apps can use what. For example I can't understand why Word would need to access location info so I disabled that. There might be apps using services that they are not meant to use
• Finally, keep wifi/cellular off when you don't need to have them on. The toggles in action centre are pretty fast so it doesn't take much time in switching internet on/off
• Disable auto update of apps, you only update when you are ready and not when you are in need of critical things

Hope this helps you

Would you mind give the dimensions of the 650 battery and perhaps picture of it? It seems you like to experiment on something unconventional. I'm curious too.
I have searched for some pictures, but WC app doesn't have the fx to upload one yet. Too lazy to open my laptop.
Lumia 650 2000 mAh 3.8 V 7.6 Wh
Lumia 640 2500 mAh 3.8 V 9.5 Wh
Dimension-wise, I'm not sure. But I noticed the text on L640's battery runs shorter in one line than L650's which I assume means that L650's battery is longer. If you give the measurement of L650's battery, I may try measure my L640's.
