WhatsApp for LG X power2

The X power2's 4500mAh cell is large, but a worn-out battery after years of charge cycles plus background apps will drain it fast. Go to Settings > Battery to see which apps consume the most, enable Battery saver, and lower Settings > Display > Brightness and screen timeout. If standby drain is still severe, the battery has likely degraded, which is the main reason an old high-capacity phone stops lasting all day. See how others solved this on Reddit

Yes. LG has fully exited the phone business and its update and account servers are being shut down, so the X power2 receives no further security patches and some LG cloud or bridge services may stop working. Back up anything stored in an LG account, and turn on Google backup under Settings > System > Backup (Backup to Google Drive) before those servers go dark. Treat the device as end-of-life for sensitive logins. See how others solved this on Reddit

The X power2 has a non-removable battery, so you can't simply swap it yourself, and the phone generally won't run on the charger alone with a fully dead battery because the charging circuit isn't designed to power the board directly. If it only boots or stays on while plugged in, that's a strong sign the internal battery is exhausted and needs a service-center replacement rather than running it battery-less.

On the X power2's Android, PDFs usually open in Google Drive's PDF viewer or whatever LG file/document app is installed. To set or reset a default, go to Settings > Apps, tap the current PDF app, and choose Clear defaults, then open a PDF and pick your preferred app (install Adobe Acrobat or Google PDF Viewer/Drive from the Play Store if needed) and tap Always.

Open the Messaging app, tap its menu, and look for Emergency alert settings, or go to Settings > More/Advanced > Wireless emergency alerts. There you can turn off Extreme threats, Severe threats, and AMBER alerts; presidential/national alerts often can't be disabled on Android. You can also toggle the alert sound and vibration there to keep them quieter. See how others solved this on Reddit

Not really, the X power2's 5.5-inch screen is comfortable for one-handed use, which many users still prefer over today's oversized flagships. If text feels small, raise it under Settings > Display > Font size and Display size. For battery longevity the modest 720p screen is actually an advantage over power-hungry large high-res displays.
